Asus Zenbook UX31A - anybody using?

Been out having a look at some Ultrabooks today.

Pretty poor selection really, most very cheap ones with HDD rather than SSD.

The three with the sort of spec I want are:

  • Asus Zenbook UX31A
  • HP Spectre XT
  • Samsung Series 9

i also looked at a Lenovo but I can't remember the model no and it was pretty big for an Ultrabook.

Anybody own any of these? On initial impressions the Asus was the most impressive but the Verge review slated the Touchpad.

Any others I should seek out? I won't buy Dell ( bad experience)

[edit]

Meant to say, I am not a big games player or video editor. Weight and battery life are important, outright power less so. Also quietness.
