The rest of the specs add up to a responsive Windows 8 experience, although had the Core i7 processor been a Haswell chip, the battery life would have likely steamed past its current 5 hours.

Aside from a few connectivity caveats (no HDMI or USB 3.0 ports on the tablet) and its weight, this is a desirable hybrid finished off with brushed aluminium.

The Asus Transformer Book TX300 may not beat the likes of the Apple MacBook Pro but it straddles the line between laptop and tablet in an admirable fashion (that would make Optimus Prime proud).

Toshiba Satellite P70 - £1,199 / US$1,992 / AUS$2,222

Toshiba Satellite P70

Aspects of the Satellite P70's build look a bit cheap, but that's not the case with the components that have been used inside the chassis. It packs a vivid Full HD screen, a stunning 2TB of storage, a top-end Core i7 chip, even a Blu-ray writer and, to top it off, discrete graphics.

Unfortunately, all of those demanding internals also mean a hit to the battery life, which lasted only 77 minutes, which isn't enough time to watch the average movie. This Windows 8 machine is intended to be a desktop replacement and as such it will hit most, if not all, of the requirements.

Samsung ATIV Book 9 Plus - £1,200 / US$1,400 / AUS$1,600

Samsung ATIV

Samsung was one of the very first PC manufacturers to jump on the Ultrabook bandwagon. It's done a fine job of representing Intel's baby ever since, with some stunning offerings, including the Series 5 Ultra Touch and, more recently, the top-of-the-range Series 9 NP900X3D.

Samsung certainly knows its stuff when it comes to Ultrabooks, but the goal posts are always moving. So what new trick can it pull out of its sleeve for 2014?

Asus G750JX - £1,269 / US$1,900 / AU$2,300

Asus G750JX

When you buy a high-end gaming laptop like this, you're not only buying something that's physically large, you're also buying power - and a considerable amount of power at that.

The Asus G750JX boasts top-end components across the board, but nowhere more so than at its hugely capable heart - there's a Core i7-4700HQ processor on board from Intel in there. Launched mere months ago, this 2.4GHz quad-core processor has plenty to offer gamers.

HP ZBook 14 - £1,430 / US$2,349 / AUS$2,617

HP ZBook

This is Dell's Ultrabook workstation, which aside from good all-round performance means it's got business squarely in mind. This includes easy access to the internals for IT departments wanting to do quick upgrades or replacements, and a fingerprint sensor for slowing down any opportunist wishing to rifle through your confidential documents.

The ZBook isn't light for an Ultrabook but it will handle all the intensive data tasks you can throw at it with its high-end Intel Core i7 chip, 240GB solid-state drive, 16GB of RAM and extra graphical grunt via discrete AMD FirePro M4100.

Battery life was distinctly less impressive at 3 hours when taxed, but make no mistake this is a capable Windows 8 workstation.

Dell Precision M3800 - £1,499 / US$2,498 / AUS$2,791

Dell Precision M3800

This is an exceptionally powerful and portable workstation for creative work, albeit with a limited battery life of around 3 hours.

An Intel Core i7-4702HQ quad-core processor backed by 16GB of RAM and Nvidia Quadro discrete graphics give this Precision M3800 almost desktop-like performance.

Another HD+ display makes a welcome appearance with a resolution of 3,200x1,800, which makes for crisp viewing. As it currently stands, however, Adobe has hobbled this great display for serious design work as it hasn't been scaled up for Creative Cloud apps. As a result, icons are tiny and menu information remains very hard to read. This isn't Dell's fault but it may take time for the situation to be resolved with all the software you use regularly.
