It's not an ultrabook, but the dell 14z is only 4 lbs and thinner than any laptop I've owned before. I got it for around $400. It was the only black friday sale laptop that had an i5 but not a dual graphics card (such as nvidia optimus, which you can get working in linux, but sometimes is a pain). Everything worked flawlessly with ubuntu, and when I dual boot to windows, plenty of games work fine, too, including the new microsoft flight simulator.
