3/ Acer Aspire Timeline U M5
A business ultrabook with gaming credentials you say? How's about the Acer Aspire Timeline U M5 which packs not only an Intel Core i5-3317U 1.7GHz CPU with 6GB of RAM, but a powerful Nvidia GeForce GT640M graphics processor as well?

While we're not advocating killing work hours killing zombies (virtually, of course) the GT640M packs the latest GeForce architecture meaning an unrivalled Ultrabook multimedia processing performance – fantastic if your work-load includes graphically intensive tasks.
It also packs a 15.6-inch display, which is rather large for an Ultrabook – making it fantastic for presentations when you're out in the field. And even though the pixel resolution is a fairly standard 1366 x 768 – not enough for native 1080p playback – there is a real crispness and brightness in the display that almost makes up for it.
The M5 also benefits from a built-in optical DVD RW drive and also features two USB 3.0 ports for fast data transfer times.
During use the chassis keeps cool and the engine room quiet, and the overall impression is that you're dealing with a premium machine. Whether or not the M5 is the right purchase for your business comes down to how much you value dedicated graphics.
If you want a portable workstation, there are better suited machines. However, if you want a lightweight machine with graphical prowess the M5 could be just the ticket.
2/ Apple MacBook Air
The Apple MacBook Air may not officially be described as an ultrabook, however it ticks all the requirements, so it's in.
And how could we resist the best looking laptop available? A laptop that set new standards for design, portability and power in small packages.
It is a design, however, that is perhaps becoming a bit tired. The 2012 Air refresh packs the latest tech in the same slimline chassis that we originally fell in love with way back in 2010.
The Air boasts a ridiculously thin unibody aluminium machine that measures just 3mm at its slimmest point and 17mm at its thickest. There are two display size options, 11.6-inch and 13.3-inch, with the smaller of the two weighing less than 1.1kg and the larger just 270g more.
The most notable change for 2012 comes by way of the CPU, which has been souped up with Intel Ivy Bridge power. The 11-incher features a 1.7GHz dual-core i5 and there's a 1.8GHz i5 CPU for the 13-inch.
For storage it's SSD all the way - the cheapest option offers just 64GB of flash space, although you can go up to 512GB of storage for a whopping £640 extra.
In a market place that's becoming ever more congested with slimline Ultrabooks, Apple is still leading the way in the cool stakes – although, at last, there are some serious challengers to its throne.

1/ Asus Zenbook Prime UX31a

The display because is the first jaw-dropping moment that you'll experience with the Prime. It boasts a Full HD, 1920 x 1080 IPS panel. That's over 2 million pixels for your eyes to focus on, with an incredible pixel per inch count of around 165.
