I've been looking for a new laptop recently and the Asus UX31A seems to crop up often, and there is a Touch version (I haven't actually used either the touch or non-touch versions so this is a bit of a pointless comment).
The trackpad was atrocious when I first got it, but they rolled out some driver updates and now it's really good.
The keyboard is sub-par but doesn't bother me too much, and the newer Zenbooks have much better keyboards.
Other than that, everything is awesome. In hindsight I would have waited for the UX31As with the better keyboards but still, I'm not disappointed. It's probably one of the best computers I've ever owned.
