Acer Aspire One

Regardless of which model you go for, the Aspire one is fantastically usable. It might be a couple of centimetres wider than any of its Eee branded rivals, but Acer has put that extra space to good use. The keyboard stretches all the way to the edges of the chassis and the keys are taller and slightly wider than those on the Eee; a change which is enough to make longer stretches of typing a far more palatable prospect. The half-height enter key still takes a little getting used to, but where the Eees limit you to short bursts of typing, the Acer is far more capable.

Other elements aren't quite as praiseworthy as, like the HP Mini-note 2133, Acer has shifted the mouse buttons to the left and right hand side of the trackpad. The positioning of the buttons takes some getting used to, but they do at least respond with a crisp click - a clear improvement on the HP Mini-Note's spongy efforts.

The Aspire one's screen more than makes up for the trackpad's shortcomings. At 8.9in from corner to corner and with a native resolution of 1,024 x 600, it effortlessly matches that of Asus' premium 900-series Eee's. Side-by-side with Asus's pricier Eee PC 901, the Acer is just as bright, and only loses out to its rival with its slightly murkier colour reproduction. It's not a big difference, but skintones looked just that touch more lifelike on Asus' Eee.

Peer around the Aspire one's smoothly-contoured sides and connectivity is ample: VGA, Ethernet, USB and an SDHC slot adorn the Acer's left-hand side, while two audio sockets, another couple of USB ports and a 4-in-1 memory card reader lie to the right. The extra SDHC slot is a real boon, though; fill it with a high capacity SD card and you can supplement the basic model's storage quickly and easily. Should you opt for one of the mechanical hard drive options, you can use the SD card as a shock-proof storage medium for your most crucial business data.

If there's one major stumbling block with the Aspire, it's battery life. All the models share the same 2,200mAh battery at their rear and, while sitting idle, our review unit lasted a disappointing two and a half hours, even with the screen set to middling brightness. An extra battery comes as a £68 extra, a supplemental cost that brings the Linux-equipped Aspire one's price dangerously close to that of Asus' Eee PC 901, whose single 6,600mAh battery lasted over eight hours.

Battery life is a huge stumbling block, no doubt there, but where buying a spare battery is easily done, improving the lacklustre keyboard of the Asus Eee, or the poor performance of HP's Mini-Note 2133, is pretty much impossible. And, with that firmly in mind, we find it difficult not to like the Aspire one.
