Toshiba AC100-10Z

Far more important than this, though, is that the 10.1in screen looks great – in terms of quality it rivals the best netbooks. The keyboard is mediocre, with bouncy keys that don’t provide much resistance, but the keys are well sized so we had no difficulty typing at speed. The trackpad and mouse keys are big and responsive too.

The Toshiba AC100 looks great and usability scores are high thanks to a super keyboard. But Android just doesn't work in this format. Without the capacity for document editing it doesn't function well as a portable computer, and without the Market it doesn't work well as an Android device.

If Toshiba can manage to squeeze Ubuntu into the AC100 and preserve its battery life, it could be onto a winner. The company estimates up to 8hrs of runtime from a full charge, or 180hrs – over a week – of standby. In practice, we managed around six hours of solid web browsing over WiFi, and even longer if we were just watching video. The Tegra 2's 1080p abilities also live up to NVIDIA’s promises, as long as you have a file format which Android can play; that means yes to H.264, MP4, AVI and XviD, but no MKV. Still, given the mere 8GB of internal storage, you won’t be able to keep many files on the AC100 itself; thankfully it’ll recognize up to 32GB SDHC cards.
