Also consider the UX32A [edit: I meant UX31A], which doesn't have switchable graphics (which don't work well under Linux anyway), has an SSD instead of an HDD (good), doesn't have upgradable RAM (bad), and is cheaper. Same screen on both.
Hmm, I can't seem to find a machine with these specs. Especially I can't find one with Full HD screen. Maybe because I am searching in European stores... (where I live)
On the other hand, I found a UX32VD with 2x256 GB SSDs. This is a little too much. Also I don't need the nVidia graphics card.
But in general, the Zenbook is probably my current favourite.
