The long-awaited version 2.0 update for the BlackBerry PlayBook OS will finally be released on 21 February according to reports.

The news comes from n4bb.com sources who confirmed the release date for the PlayBook 2.0 OS.

When the BlackBerry PlayBook was launched last April there were a number of short-comings with the tablet which RIM promised would be resolved in a software update.

Still waiting…

We're now in February 2012 and the update has yet to materialise but this latest news will bring some comfort to the PlayBook's long-suffering fans.

The PlayBook 2.0 update is set to feature native email, calendar and contact apps, meaning users will no longer have to bridge their BlackBerry phone with the tablet just to work these trivial apps.

Unfortunately there will not be a native BlackBerry Messenger (BBM) app so a BlackBerry mobile will need to be connected via the BlackBerry Bridge for access to be gained.

The Pirate Bay has announced that it is to duck out of the torrent hosting game and instead focus on offering magnet links to its users.

On the surface this looks like a bit of a blow for the soon-not-to-be-a file-hosting site, but it is actually a shrewd move by the folks behind The Pirate Bay as it will make the site harder to pin down in court for copyright infringement.

That's because a magnet link doesn't actually have any file information, just some data. Client apps then take this data and find the file associated with the link.

It's obvious why The Pirate Bay has chosen now to change tack: the site's owners have been refused an appeal to their charges for copyright infringement and this has meant a number of significant changes have had to happen.

(Not) breaking the law

The biggest of these changes was the change of the domain from thepiratebay.org to thepiratebay.se – this is so the site doesn't fall prey to any messy US laws.

The Pirate Bay will now be a lot leaner and in turn much easier to host, so expect a number of mirrored sites to pop up just in case the main site is blocked for any reason.

All of this adds up to yet another headache for the likes of the MPAA and the RIA. In short, by forcing The Pirate Bay to make changes, the site may well be stronger than ever.

"Quite some time ago we decided to not host torrent files anymore," said Pirate Bay about the change in direction.

"In following with that decision, we decided to make Magnet links the default option for the Download buttons!

"We've just changed places on the links. Magnet is now default, Download torrent is now where the magnet links used to be. The reason is the same as always: Magnets are now good enough to use, and it's not as easy to block as .torrent files. Also it saves us a huge amount of bandwidth!"

It also revealed that the site will be completely torrent free (unless the torrent is shared by 10 peers or under) as of 29 February.

After the major update of the Windows Phone operating system last year in the form of Mango, it looks like Microsoft is readying the next instalment of its mobile OS.

Where as Mango brought radical change, Tango is expected to be a minor update, filling the gap until the next major version rumoured to be Apollo later this year.

So can you expect the Tango update to be "of Latin-American origin, danced by couples, and having many varied steps, figures, and poses"? Well, it's not a dance routine, so no – but we've handily put together what could be expected below if you prefer your Latin beats locked into phones.

Windoews Phone Tango: Release Date

As the rumour mill hots up with MWC 2012 gossip it's looking ever more likely that Microsoft will unveil its latest update to the Windows Phone operating system in Barcelona.

With a late February announcement we would expect to see the first Tango touting handset hit the selves in April/May - especially as a Q2 launch was confirmed in a leaked document by Nokia.

Windows Phone Tango: Minimum specs

There is little detail on what the minimum spec requirements would be for a handset to run Windows Phone Tango, but seeing as it looks set to land in the budget market we can expect it will support single-core processors with less than 1GB RAM - and possibly as low as 256MB.

Expect Tango phones to run lower screen resolutions and entry-level cameras, with some possibly not even featuring cameras at all.

Windows Phone Tango: Features

A signal of Microsoft's intentions to push Windows Phone Tango out to developing countries is the report that the latest iteration will support 120 different languages.

This is a dramatic step-up from Mango which supports 35 and also way ahead of rivals with iOS providing support for 34 and Android 55 languages.

We've also heard that the Skype app will be appearing on Windows Phone soon and Tango could signal the integration of Skype and the likes of Google + into the messaging functions.

There has been lots of rumours that NFC support will hit Windows Phone with the Apollo update in late 2012, but there is an outside chance we could see it included in Tango – as rivals look set to embrace the tech in their mobile devices this year.

Windows Phone Tango: New models

An operating system is nothing if there is no hardware for it to run on, so let's take a look at the handsets which may be championing Tango straight out the gates.

The Nokia Lumia 610 is highly tipped to be announced along side Windows Phone Tango at MWC 2012 in Barcelona as one of the first phones to run the latest OS.

This budget handset looks set to be PayG only - with a bargain bucket price tag and specs to match. It could even land at sub-£100 which would certainly spark some concern among other budget phone manufactures and may lead to a favourable price drop for consumers.

There are murmurs surrounding the Nokia Champagne which appeared in the 'I'm a WP7!' app back in October last year.

There are no details on the Champagne and it could well be the development name for the Lumia 610 or a network-specific version of the Lumia 800 – never-the-less we will be keeping track of this boozy proposition.

Windows Phone Tango: Price

According to long-time Microsoft commentator Mary-Jo Foley Tango will be aimed at the budget handset market and according to one source "all about Nokia".

Therefore we expect to see phones packing Tango fall into the cheap-as-chips category – although there may be few devices which make it to the UK as it has been suggested that Tango "may be focused largely on the Asian market".

We're anxiously awaiting to see which version of the OS the Nokia Lumia 610 is running - although a sub-£100 price tag hints at Tango, we're wondering if it will manage to use that OS given it will only have been announced a month or two previously.

More information will undoubtedly leak out in the lead up to the announcement and we'll keep this page updated with all the latest news regarding Windows Phone Tango.

HTC could be about to enter the music streaming fray at MWC 2012 with a branded Spotify-competitor created as part of its partnership with Beats Audio.

Rumour has it that HTC is working closely with music industry mogul and Beats' head honcho Jimmy Iovine to create the streaming service after talks with existing companies, including Spotify, failed to go anywhere.

The as-yet unconfirmed music service would come as the default player on HTC phones and tablets. GigaOm's source couldn't provide any pricing details so we don't yet know if the service would be bundled with devices or if you'll have to cough up a monthly fee to use it.

HTCify

But why would HTC, a handset manufacturer, bother sticking its oar into the previously unrelated music streaming market? Same reason it gave movie rental a whirl in the not-massively-successful-thus-far HTC Watch: differentiation.

All the phone manufacturers work within the parameters of the OSes their products run, so any move they can make to differentiate their products from the milieu and create some kind of user loyalty is going to be worth a punt.

Particularly as the bloom seems to have come off the HTC rose in recent months, with the company's meteoric rise to top Android maker tempered by falling sales and dipping profits.

Nikon has revealed how many units of the new Nikon D800 semi-pro camera it intends to manufacture at its Sendai factory in Japan.

According to a report which appeared on Bernama, Malaysia's National News Agency, Nikon is aiming to produce 30,000 units of the D800 per month, while it also revealed that it is hoping to produce 5,000 Nikon D4 units every month.

Several Asian journalists visited the Sendai factory, with Nikon President Jiro Saito telling them that it had spent US$100 million repairing the factory after the devastating earthquake of March last year.

Camera every minute

Currently, the factory has around 1,600 workers, having the ability to produce one unit of camera per minute on a daytime shift. According to the report, a D800 can be produced in around four hours, while the D4 takes five.

Some components for camera production are sourced from overseas factories including Nikon China, with around 1600 component parts required to produce both the D800 and D4.

Both the new cameras were announced this year, with the D4 back at the beginning of January and the D800 just last week.

The D800 features a 36 million pixel sensor, making it the highest resolution full-frame camera in the world.

Originally slated for a mid-February release, recent reports have suggested that the D4 could be delayed until the middle of March. Meanwhile, pre-orders for the D800 were frozen in the US leading to speculation that there could also be a delay on those too.

Apple is seeking to sue Kodak over an alleged patent infringement relating to Kodak's printers, picture frames and cameras.

It's safe to say that 2012 hasn't been a good year for Kodak. After filing for bankruptcy protection in January, last week the company announced it would no longer be making cameras in a bid to restructure and save it from going under.

Over the past few years and months, Kodak has relied on selling off its extensive patent catalogue and launching law suits against a variety of companies for infringements on those patents.

However this time, Kodak is on the receiving end of a patent infringement lawsuit - and from the mighty Apple. Currently waiting for approval from a New York Court, Apple alleges that Kodak has infringed on technologies used in printers, digital cameras and digital picture frames.

Foes

Kodak and Apple are old enemies, having fought over patents previously. A ruling in June 2011 went against Kodak, with Apple claiming that it shared camera patents with the company.

If the US Bankruptcy court approves Apple's request to sue Kodak, the next stop is the International Trade Commission and the US District Court in New York.

From there, if Apple was to win its case, it could see core products from Kodak withdrawn from sale, which won't be good news after recent troubles.

Last week's announcement suggested that the company would be able to save $100million if it stopped producing cameras, with it even hinting that recently announced cameras at CES back in January will never come into being.

Android claimed over 50% of the smartphone market share in the last three months of 2011 which sees Google's mobile OS appearing on one in two smartphones.

According to stats gathered by Gartner the smartphone market witnessed huge growth in Q4 of 2011 with sales to end users reaching 149 million units - a 47.3% increase from the fourth quarter in 2010.

This boost in sales resulted in Android claiming 50.9% of the smartphone market, up from 30.5% in the same quarter in 2010. Apple also saw an increase in market share for its iOS system as it claimed 23.8% in Q4, up from 15.8% in 2010.

Symbian down as new kids storm in

Nokia's Symbian OS on the other hand saw a large drop in the smartphone market share, slipping down to third place with 11.7%.

It's not all bad news for Nokia though as Gartner reports that it's still the number one global vendor of mobile devices – with its entry level handsets widely shipped to Asia and other developing countries.

Emerging manufactures such as ZTE and Huawei have started to stake a claim in the mid and low-range smartphone markets and both companies saw gains during the last quarter of 2011 as they became the fastest growing mobile vendors after Apple.

ZTE is now the fifth largest mobile devices vendor in the world after it shipped 56 million handsets in 2011.

The increased presence of these newer companies has helped Android take the majority share in what is a very competitive smartphone market.

Gartner predicts Android's position will strengthen further in early 2012 as Apple's delayed launch of the next iPhone will see a decline in sales in the first two quarters of the year.

How Sony is trying to save the world

Sony is famous for a lot of things.

Most recently it's been the launch of the PS Vita and some disappointing financial results that have been getting the headlines.

But one thing Sony hasn't had much coverage over is its work to reduce its impact on the environment.

Of course, any manufacturer of oil-based plastic products creates a sizeable carbon footprint but Sony has become a shining example to other electronics manufacturers by committing to completely eliminate its negative effect on the environment by 2050.

The road to zero

The story starts at Sony's 25-storey, 124,041 square metre Osaki Home Entertainment HQ in Tokyo. Unbelievably, it only took a single year to build.

It's the very first building of its kind to use a natural 'bioskin' cooling system, and TechRadar was lucky enough to be invited to visit earlier today.

The bioskin is made up of a network of porous ceramic pipes that are made using soil. Rain water is collected from the roof of the building throughout the year and during the hot Japanese summer, the water is pumped back up through the pipes on the outside of the building.

The water penetrates the ceramic and evaporates from the pipe surface, which cools the surrounding air by around 2 degrees. This shields the building from the sun's intense heat and reduces the load on the CO2-producing air conditioning systems inside the building.

It's the kind of cutting-edge green-thinking that Sony is applying to many of its consumer electronics projects.

TVs made from old DVDs

Sony has also recently developed a new material for its products which is made from 99% recycled plastic. The material is called SoRPlas and is made from recycling old products.

Discarded DVDs are blended up and the metal film from their surface is peeled away. The optical sheets from discarded LCD TVs are also shredded and the resultant shrapnel is blended with the DVD fragments. The strength and stiffness of the recycled plastic can be manipulated according to the proportions of the mix.

This mix is then added to some dye and a very small amount of flame-retardant to make the plastic fireproof, and the resulting material is a plastic that's every bit as good as more 'fresh' plastic.

Using this method, Sony is now able to build products like earphones and its packaging from 100% recycled plastic. It's also now being used to build the bezels of some of Sony's TVs, while 80% of the plastic used in the HDRTD20V 3D camcorder is made from this SoRPlas material already.

Using this material means 77.3% less CO2 is produced compared to conventional plastic, and the aim is to use SoRPlas to replace as much plastic as possible across all of Sony's many factories.

The first step in Sony's 'road to zero' is to harness the environmental benefits of SorPLas to reduce the company's resource consumption by 30 per cent and its CO2 emissions 20% by 2015.

Life cycles

But the goal extends beyond manufacturing. Sony's ultimate aim is to include product life cycles into the zero-emissions plan, which means building energy efficient, environmentally friendly products and packaging.

That means recycled materials wherever possible, eliminating the use of hazardous mercury, developing more efficient solar cells, increasing power efficiency in products, reducing the size of packaging and developing more environmentally friendly battery technologies.

Sony has already ceased production of old-style LCD TVs, with 100 per cent focus on more efficient LED tech. This also means sets can be thinner, using less materials - and has the further effect of requiring smaller boxes.

The bio batteries are also very interesting - they feed renewable glucose and oxygen to natural enzymes to generate electricity. This tech is a way off being used in your everyday smartphone, but it's being developed and looked at very optimistically.

While the zero emissions goal is still very far away, it's initiatives and innovations like these that will make future generations wonder what kind of barbaric tree-hating gas guzzlers we really were.

Canon has said that even though compact camera sales are experiencing a general downturn, people are investing more in individual cameras purchased.

According to industry analysis, 2011 saw a 30% drop in the number of compact cameras sold, with smartphones with ever better cameras being pinpointed as the cause.

However, Canon, which though probably best known for its DSLRs, also manufacturers a wide range of compact cameras says these figures aren't worrying.

Canon UK's David Parry told TechRadar, "People are looking for different things in cameras now, a different design, a different look.

"They're looking for big zoom lenses in small cameras, that's what we're seeing and that's what people are asking for - they want big specifications, but they want them in tiny bodies."

Long zoom

We've seen a speight of compact cameras recently announced with huge optical zoom ranges. Where once the megapixel was king, now it seems marketeers have a new high number to push.

Canon's own IXUS 510 slots into its "stylish" range of cameras, but still manages to pack an impressive 12x zoom into its slim body.

Parry believes it is cheaper compacts that are really suffering. "What we're seeing is that people are investing more in digital compact cameras, the quantities might be going down, but the quality of what people are buying, the higher end cameras, isn't."

"At the moment smartphones aren't the answer to a good quality compact camera. They don't have the low light capability, they just can't capture the motion and they don't have the added features that you get from a quality compact."

"Canon plays in the higher end of the market, and we're still producing what we think are market leading cameras. There is nothing else like an IXUS camera out there, and that's where we're seeing the growth and the interest in the market."

Samsung has hinted that it may sell off its LCD TV making arm in order to focus on the more lucrative world of OLED TVs.

The news jives nicely with Samsung's earlier public mulling over the possibility of bringing its OLED display business, Samsung Mobile Display, in-house.

Play it off, keyboard cat

If you're staring sadly at your Samsung LCD TV and wondering where it all went wrong, we'll tell you: money.

LCD TV prices have steadily fallen over the past few years thanks to a flooded market and falling demand for LCD – it means that Samsung makes a loss on each LCD TV sold.

As if that wasn't bad enough, Samsung's LCD unit sales fell 10 per cent in 2011 due to lacklustre demand as well, so selling the entire unit off would make a lick of sense.

Much more enticing is the brave new world of OLED displays. Currently the darling of the smartphone and tablet world, OLED TVs are slowly but surely infiltrating the living room.

Samsung itself has a very lust-worthy 55-inch OLED TV heading to the UK in the second half of this year.

However, it is worth mentioning that Digitimes thinks Samsung will keep the LCD business and pump $6 billion into it in a bid to make it work. But, you know, Reuters v Digitmes. Who do you believe?

Now watch our video of the Samsung 55-inch OLED TV in all its glory while you mull that conundrum over:

Zynga, creator of the addictive FarmVille and Words With Friends games has released its Q4 earnings report showing huge growth, but also a net loss.

Q4 revenue hit US$311.2 million, a 58.9 percent increase on the same time last year.

Revenue figures for the entire year were even more impressive, showing a whopping 90.8 percent increase from 2010 to 2011 of $1.14 billion.

However despite this, the company posted a net loss which it attributed to expenses involved in the company's IPO and investment in new game development.

Pushing FarmVille, gaining users

Not that it's a cause for concern, as monthly active users hit the 240 million mark, up 23 percent from last year, and "monthly unique payers" climbed to 2.9 million.

It was recently discovered that Zynga is worth $445 million to Facebook which earns a cut of the Facebook credits used to buy items in games like Farmville.

Zynga is understandably optimistic about 2012, predicting yet more growth, although weighted towards the second half of the year.

Apple CEO Tim Cook took to the stage at the Goldman Sachs Technology and Internet Conference last night to deliver the keynote speech.

During the speech he covered topics from Apple factory working conditions, to how he intends to run the company in the absence of late CEO Steve Jobs.

Company direction

When asked what he was determined to maintain now that Steve Jobs is no longer around, Cook said: "Steve grilled in all of us over many years that the company should revolve around great product, and that we should stay extremely focused on just a few things rather than try to do so many that we do nothing well. We should only go into markets where we can make a significant contribution to society, not just sell a lot of products.

"And so, these things, along with keeping excellence as an expectation of everything at Apple, these are the things that I focus on because I think those are the things that make Apple this magical place. We're always focused on the future. We don't sit and think about how great things were yesterday. I love that trait. I think it's the thing that drive us all forward."

Price competition

Responding to a question about tablets, Cook went into why Apple isn't in a hurry to start a price war with competitors, saying: "Price is rarely the most important thing. A cheap product might sell some units. Somebody gets it home and they feel great when they pay the money, but then they get it home and use it, and the joy is gone.

"The joy is gone every day that they use it until they aren't using it anymore. You don't keep remembering 'I got a good deal!' because you hate it!"

Factory working conditions

Working conditions at factories manufacturing Apple products has been a hot news topic recently, and Cook gave a statement about the company line during his speech.

Addressing a question on the issue, he said: "Apple takes working conditions very, very seriously, and we have for a very long time… Our commitment is simple: Every worker has the right to a fair and safe work environment, free of discrimination, where they can earn competitive wages and they can voice their concerns freely.

"Apple suppliers must live up to this to do business with Apple. If we find a supplier that intentionally hires underage labour, it's a firing offense."

This tallies with Tim Cook's recent email to Apple staff assuring them that he was taking the matter in hand and his invitation to the Fair Labor Association to inspect working conditions for itself.

The price of calling mobile phones from your landline will fall by a whopping 85 per cent by April 2015, a legal tribunal has confirmed.

Following years of arguments between phone companies and regulators, the Competition Appeals Tribunal (Cat) has decreed the scale of the cuts, knocking up to £800m off Britons' phone bills.

The cuts, which will continue to happen progressively over the next three years will see the cost-per-minute rate fall from 4.18p to 0.65p. Costs have been falling since April last year.

The final figure is even lower than the recommendation made by Ofcom, who welcomed the ruling, saying it would "reduce significantly termination rates which will bring competition and consumer benefits".

Wrangling

In the wake of the tribunal's verdict, Vodafone itself has warned that landline providers BT and Virgin may not be so keen to pass the savings onto its customers.

In a statement, the network said: "The fixed-line operators have merely pocketed previous reductions in mobile termination rates, instead of reducing prices for customers. BT, meanwhile, has actually increased its line rental prices three times over the past year and a half."

The company, which called the cuts "Draconian" says poorer customers will lose out as a result.

It says it will have to compensate for lost revenue by removing subsidies for pay-as-you-go handsets.

A new television service called Aereo will give viewers the opportunity to watch live broadcast television networks over the internet on devices like the iPad and laptop computers.

Aereo will begin a trial in the New York City area on March 14th and will allow live HD streaming of major networks including ABC, NBC, CBS, Fox, PBS, CW and a host of local channels.

The $12 a month service aims to help people end dependence on expensive cable contracts and free network television from the 'closed circle' enforced by cable providers.

It is able to legally stream the live TV over-the-air directly to your devices thanks to tiny thumbnail-sized antennas (one per user), which are stored together in a company data center.

From there you can use the HTML5-designed Aereo.com website to view content on tablets, smartphones and even on the big screen with devices like the Apple TV and Roku set-top boxes.

Remote DVR functionality included

The service will also give users the opportunity to record 40-hours of shows from the TV guide with their own personal remote DVR that again doesn't require a set-top box or a cable subscription.

The service is primarily aimed at the casual TV viewer who has no desire to pay over-the-odds for cable channels like HBO and ESPN and is happy with the network offerings.

"If you have this and you have Netflix, you absolutely have the ability to not have a standard cable subscription," said Chet Kanojia, Aereo founder and CEO.

So, instead of paying over $100 a month for a cable TV package, viewers will soon be able to take advantage of Netflix, Hulu Plus and Aereo for around $30 a month.

One of the key backers Barry Diller told the New York Times: "Anyone will tell you, whether it's Amazon or Hulu or Apple, that they can't get enough programming that people want to see to – so to speak, 'break the chain' — because all of the programming is controlled within the circle.

"[Aereo] pries over-the-air broadcast television out of that closed system," he added.

New Yorkers can register their interest in the service at Aereo.com.

HTC will be the first manufacturer outside Sony to gain PlayStation certification for its Android phones and tablets, according to reports.

Pocket-lint claims it has been informed by sources that the announcement will come during 2012, possibly as soon as this month's Mobile World Congress expo in Barcelona.

The PlayStation certification scheme brings classic PSOne games to Android devices and was planned as a cross-platform initiative.

However, until now only Sony-branded devices like the Sony Ericsson Xperia Play have the nod.

Among the PlayStation Certified games already available are Crash Bandicoot, Bruce Lee, Asphalt Adrenaline 6, Splinter Cell: Conviction.

2012 boost for HTC

An announcement would be a major boost to the Taiwanese manufacturer as the 2012 mobile landscape begins to unfold.

The company endured an underwhelming 2011 which it attributed to flooding the market with too many devices and confusing its customer base.

After acquiring Beats Audio in 2011, it looks like the early Android pioneer will have an improved gaming, as well as listening, experience as the year progresses.

HTC itself has not commented on the story.

Lovefilm's days may be numbered as speculation rises about Amazon creating a global video service.

Lovefilm is also shedding management. Last week, Lovefilm's CEO Simon Calver stepped down, while today it emerges that the company's chief technology officer, Mike Blakemore, is leaving to join the Guardian.

That might not sound like much, but two of a business's top brass ditching Lovefilm within a week is pretty dodgy going for any company.

Two step

This staffing shuffle has led some to speculate that Lovefilm's days as a stand alone brand may be numbered – it has already been bought by Amazon and the latest thinking is that the retail behemoth will completely absorb it in the near future.

Amazon has already been bolstering its US streaming service as it steps up the fight against Netflix and adds to its Kindle Fire media arsenal. And you can bet that it'll want to bring all its streaming products under one banner at some point.

At that point, Lovefilm would cease to be. The question is, is that point coming soon?

A spokesperson for Olympus has said that he believes the number of lenses available for its range of Micro Four Thirds cameras gives it the edge over competitors.

Olympus announced the Olympus OM-D EM-5 last week after weeks of speculation and rumour, bring the total number of mirrorless models currently in the Olympus range to four.

Last year, its PEN series of cameras updated to its present three models, which includes the Olympus PEN E-P3.

Speaking to TechRadar, Mark Thackara, UK marketing manager for Olympus said, "Now the OM-D is out, we've got the advantage. We give people a lot of choice and there's a lot of lenses to choose from."

Thackara believes that customers for the OM-D will be both existing Olympus users and those looking for a "serious" compact system camera.

"Up until now the serious lenses [in the Olympus range] hadn't really had a camera to go with them, it's fair to say," Thackara explained.

"While the E-P3 is a good partner for some of them, a lot of people who buy that don't want to buy extra lenses, but I think the new camera will do a lot better for us in terms of accessory sales."

Sales figures

Thackara said that lens sales were generally good, but admitted they could do better. "We need to produce lenses at prices that are very attractively priced, and that will make a big difference."

Most of the major camera manufacturers have a compact system camera in the market now, with some providing more lens choice than others.

Nikon's 1 system has a fairly limited range to choose from, but it does allow (via an adapter) for Nikon DSLR lenses to be used with the camera. Sony's NEX range is in a similar position, although it did announce its NEX lens line-up for the next 12 months at the CP+ show in Japan last week.

The E-M5 is thought to be the first camera that Olympus will produce in an ongoing OM-D line up. "The biggest clue is the lens line-up," Thackara told us.

"Some of the other compact system cameras have a very limited range of dedicated lenses, whereas we have now offer a choice of around 20, it's a very good range of options and some of them are pretty serious."

As Olympus cameras come under the Micro Four Thirds banner that was developed in conjunction with Panasonic, OM-D and PEN cameras are also compatible with Panasonic's lenses.

The OM-D E-M5 was announced last week and will be available to buy from April, with a retail price of £1149.

New rumours are suggesting that the upcoming replacement for the EOS 5D Mark II will be split into two lines, with one featuring a 45 million pixel sensor.

It's another day, and so another Canon 5D Mark III rumour emerges. Disappointed from the lack of an upgrade at last week's CP+ show in Japan, the rumour mill is now suggesting that it will in fact be split into two cameras.

We've been waiting for a new 5D, ever since, well the 5D Mark II was unveiled. Canon's biggest rival, Nikon, unveiled the Nikon D800 last week which would be the most obvious competitor to any 5D upgrade.

The D800 features a 36 million pixel sensor, while most rumours up until now have suggested that a 5D Mark III (or 5DX) would only be around 22 million pixels.

Now there are suggestions that the line will be split in two with one variant featuring a whopping, Nikon-beating, 45 million pixel sensor.

It has also been said that the pixel size would be similar to that of the Canon G1 X, the company's recently announced premium compact.

Specifications

Other suspected 5D X specs include a 61 point AF, 3.4fps shooting, ISO 100-6400 (expandable to 50-12800) and both a Digic 5 processor and Digic 4 processor (as seen on the 1DX).

Meanwhile, the 5D Mark III is believed to have a 22 million pixel sensor, 61 autofocus points, 6.9 fps shooting and ISO expandable up to 51,200.

It seems likely from those specs that the 5D X would be aimed at studio and portrait photographers who are looking for the huge megapixel count, but aren't so bothered about fast shooting. In other words, the same people that would be looking to buy the new Nikon D800.

Only time will tell if either, or both, of these rumours turn out to be true, but one of the latest rumours suggests that a new DSLR will be unveiled at the end of the month.

Canon announced it was working on a new full-frame camera back when it announced the 1DX. With Canon appearing at Focus this March after last year's no-show, perhaps we will have something to look forward to.

A mystery Motorola handset has snuck out of its pre-MWC 2012 holding pen and on to the web today, revealing Ice Cream Sandwich and Intel hardware as well as a neat new look.

At first glance, you'd be forgiven for thinking that this unnamed handset is an HTC affair, given the rounded corners at the base and overall look – it certainly makes a nice change from Motorola's regular boxy affairs.

But the big news is on the interior of the phone, with the handset said to be Motorola's first Intel phone running the Medfield platform as opposed to the company's usual TI OMAP processors.

Tasty treat

Software-wise, it's set to be Motorola's first Ice Cream Sandwich (Android 4.0) phone, and we're very much expecting to see it launch at MWC 2012 in a couple of weeks.

There isn't much more to report on the spec front, but looking at the handset you can see that it's lacking in the button department, opting for soft keys instead of physical ones.

PocketNow, which got the Moto scoop, suggests there'll be a hefty camera on board too, possibly with 15 fps burst capture.

We'll find out all there is to know about this intriguing new Motorola phone at MWC 2012 – stay tuned for our hands on review.

Which laptop should I buy?: Laptop types

Choosing a laptop can seem like a complicated task, as there are so many models on offer, and a huge range of prices.

Can you get away with something cheap, you might wonder? Or will you have to spend more? Should you focus on the CPU first? The screen, the laptop graphics card, battery life, portability - something else?

When buying a laptop, though, you should start by focusing on your own needs. How will you want to use the new system? Understand your own requirements and that will automatically give you a much clearer idea of exactly what you're after.

Consider the applications you'll want to run, for instance.

If you really only want to browse the web, send emails, write a simple letter or two, play music and watch DVDs, then just about any laptop (as long as it has a DVD drive) will do the job, and spending £300-£400 or so will give you an acceptable system.

If you'd like to edit video, though, or run other resource-hungry apps, then you'll need a laptop with a faster CPU, more RAM and storage space. Expect to pay considerably more, perhaps £600 and upwards.

And if you're after a laptop than can handle the latest games, then your system will need even more power and storage, and a dedicated graphics card, the faster the better. Prices may start at £600 or so, but if you're after decent performance then you might have to spend three times that amount, perhaps more.

Think also about how these requirements will affect the portability of your laptop.

If you're planning to edit video or play games on the system, then you'd probably also like a large screen, maybe 17 or 18-inch.

But that makes for a large, heavy laptop, and will shorten your battery life considerably - as will the fast CPU, large amount of RAM, and so on.

And, unfortunately, powerful laptops tend to be larger and have a shorter battery life, just as a general rule. There are exceptions, if you're willing to pay a lot of money, but otherwise you shouldn't expect a gaming laptop to be something you can carry around and use anywhere, for hours on end - because it's not going to work like that.

Put this all together, then, and the best laptop to buy for you should fall into one of three possible categories.

"Home" systems start with the basic browsing, email and media setup. You can extend them to handle image, audio and video editing tasks if you like, even game playing at a push, but performance won't be great: these laptops are more about value for money.

And while you can take them from room to room, or to school or work if you like, they're not designed to be hugely mobile. Expect to pay £300 to £800.

Ultrabook laptops start with more compact systems, without a DVD drive to save on weight and size, so they're very easy to carry around. Battery life will be good, allowing you to work just about anywhere. And at the high end you'll also have a powerful CPU, lots of RAM and storage space, although this can be very expensive. Expect to pay anywhere from £300 to £2000 and more.

"Power" laptops meanwhile concentrate on features above all else. You'll have a dedicated graphics card, a 17 or 18-inch display, a Blu-ray drive, and a similar level of CPU, RAM and hard drive power that you'd find in a desktop PC.

So game playing won't be a problem, but these systems will also be heavy, and have a poor battery life. Prices in this category start from around £800, but if performance is vital then you can expect to part with £1,500 - £2,000, perhaps more.

If you want ultra-portability and a very low price then you could look at netbooks as an alternative. They're low-powered, have tiny screens and don't come with DVD drives, but they're also very easy to carry around and can have a battery life of five hours or more. We're more interested in laptops in this article, but if a netbook would better suit your needs then take a look at our reviews.

Which laptop should I buy?: Power or portable

You should now have a general idea of the sort of laptop you want: either a Home, Ultrabook or Power system. But what does that mean in practice? Focusing on each category in turn will give you a better idea of which laptop to buy.

Power laptops

If you need a system that will do just about everything you can do on a desktop PC (play games, edit video or run other demanding applications), and you don't mind having a heavy laptop with a short battery life as a result, then opt for something in the Power category.

You'll want something with at least an Intel Core i5 processor, maybe a Core i7.

4GB of RAM is a must; a 500GB hard drive is probably a sensible minimum, 1TB better if you can afford it; and opt for a Blu-ray, rather than a DVD drive. Remember, you'll be looking to keep this system for 2 or 3 years, so it's wise to buy more than you think you'll need right now.

A 17 or 18-inch screen will give you plenty of room to work. And if you're looking to play games then you should ignore slow integrated graphics - that's anything with a name that starts "Intel GMA", "VIA" or "SiS"), and opt for a speedy dedicated graphics card instead.

Which means picking a laptop with a Mobility Radeon HD product perhaps, or one of the better GeForce chips. Nvidia's product range is more confusing, but you'll find more details on its site.

Great examples of Power laptops include the Toshiba Qosmio X770, which features an i7 CPU, 17.3-inch 1920x1080-resolution screen, a 1TB hard drive, 8GB of RAM and Nvidia's phenomenal GTX 560M graphics card with 3D support, all for around £1700.

And the fabulous Alienware M18x uses a powerful i7 CPU and AMD's Radeon 6900M graphics card, giving it incredible gaming performance. It weighs a hefty 5.7kg and has an 18.2-inch screen, so you're unlikely to want to carry it around with you too much, but you'll get an incredible gaming experience for your £1850.

Ultrabook laptops

If you'll mostly be using your laptop on the move - in the car, on the train, nowhere near any recharging points - then it'll need to be light, something under a couple of kilograms, and with as long a battery life as you can manage.

There are some great Ultrabooks around that offer speedy performance with light frames and small size. Look for something with a screen size of 11 to 13 inches, and you'll see plenty of Ultraportables running new low-power Intel Core i5 and i7 chips. They also use flash memory instead of hard drives. This also helps to save battery, but it actually helps to improve performance too, though it means you get less storage for the same price.

The Asus Zenbook comes in 11- and 13-inch models, with a choice of i7 and i5 processors and 125GB or 256GB of storage.

These Ultraportable machines are great for working on documents, or for generally basic computing tasks. They can handle some powerful applications thanks to their multi-core processors, but they only offer basic graphics performance, so no hardcore gaming on them.

If you're not wedded to Windows, than you should absolutely look at the Apple MacBook Air line. They offer excellent battery life, extremely fast performance and are some of the best-made portable laptops around. The 11-inch version starts from £849.

If you want portability without sacrificing features, then check out the Sony VAIO VPC-Z21V9E. It's a thin, light laptop that offers a higher-resolution screen than its contemporaries, as well as a docking stations that adds an optical drive, more ports and even a better graphics card. Of course, you'll pay for these features, to the tune of as much as £2,699.

Home laptops

You probably don't need a tiny laptop, of course. Or one with the power of a desktop. You just want something basic, which offers good value for money, and that means you're better off with a system from the Home category.

If you need to do little more than run Windows, visit your favourite websites and send emails, then you can get by with something very basic . An Intel Core i3 will offer all the performance you need when paired with 4GB of RAM and a big enough hard drive for you documents – 250GB or so.

So, for instance, the Sony VAIO VPCEH2F1E won't break any performance records, but it has a bright and clear screen, along with welcome extras such as 802.11n Wi-Fi. The battery life is average at around 3 hours, and it's a really good deal at around £450.

For around the same price, you can find some other really well-specced machines. Samsung's RV520 offers good performance from an Intel Core i3 processor, but packs in 6GB of RAM, so will be great for those who like to edit their HD movies on their laptop. The screen isn't quite as nice as some out there, but for around £450, you get no small amount of muscle.

If you want something that won't take up the whole sofa when you're using it, the 14-inch Dell Insprion 14z is a great-looking, speedy laptop that offers really superb battery life, and though it's a little more at £579.99, it's absolutely worth every penny.

There's no need to feel you're somehow being short-changed by opting for a basic Home laptop, then. This is a highly competitive market, and there are plenty of powerful systems to be had at absolute bargain prices.

General tips

You should now have a better idea about which laptop to buy, then, but there are just a few more general tips you can follow to ensure the purchase goes smoothly.

Think about how you'll need to use your laptop over the next two or three years, for instance, then decide how much you can afford to spend to achieve all that. You won't then get tempted to pay out "just" another £50 or £100 more, and if you have a set budget then it'll be easier to go shopping later: you can just ignore everything that's too expensive.

Then keep an eye on our laptop reviews and ratings, where you'll find the best laptop reviews which will quickly point you at the models you must take seriously, and the ones you really shouldn't.

When you find a likely candidate machine, try to locate one - or a similar model from the same range, at least - in a local PC store before you buy. This will let you try out the screen, test the keyboard, the track pad, maybe hear the sound quality of the speakers, all the vitally important elements that you really can't understand from a spec sheet alone.

And when it's time to buy, always use a credit card, if at all possible. Hopefully the laptop will arrive, on time and in fully working order, but if there are any issues then the Consumer Credit Act may mean the credit card company is equally liable, so giving you another way to recoup costs in the event of any problems.
