Of the Windows 8 machines we've received so far, the Asus is the only Core i5 — so although it appears on the bottom of the charts here, its performance is actually quite fine.

We've moved to a new battery test for Windows 8, a modified version of our heavy battery test for Windows 7. We loop a 720p video until battery depletion, with the screen brightness set to 40 per cent and the ambient brightness adjustment turned off.
While none of the Windows 8 laptops we've reviewed so far can be said to have amazing battery life, Asus' Taichi doesn't do well at all, and that's with only one screen active. Turn on the second, and of course things drop farther down.
The Taichi is an experiment. While some may find a use for its dual screens, and it's built well enough, the lack of a touchscreen on the interior and troubling battery life could put even those people off.
The Asus Taichi is expected to hit stores in Australia mid-November.
