Funny you mention that. I, a Linux user, was deciding between the 13" Air and this Zenbook Prime, and chose the former, because the Zenbook reportedly has lots of issues and annoyances:
Installing on the 2012 Air wasn't exactly a walk in the park either, but that wiped out any Zenbook advantage. Now that it's set up, I absolutely love my Air running Xubuntu — it's the nicest laptop I've used. I'd recommend it to anyone. And as a bonus I can reboot into OS X if I ever want to.
But this Asus on the article certainly looks good if you put Linux in it
