Usability
If there's one thing that impressed us with the Air, it's its keyboard. It's one of the best we've ever used, on any laptop ever -- ever. Then there's the gesture-sensitive multi-touch mouse -- all you have to do is stroke it and it'll do your bidding. Why can't everything be so simple? And we can't forget the 13.3-inch screen -- it's an absolute joy to look at.
The Wind is smaller, so it was always doomed to be less usable. It's not as RSI-inducingly bad as most laptops of its size, though. It's easy to touch-type on its keyboard, and although the mouse trackpad is stupidly small and lacks multi-touch, it's not too bad.
Verdict
It's got to be the Air, again. The Wind doesn't lose by much, but the Apple machine is the easiest to use on a day-to-day basis.
