Maybe it was just my system but I actually found Windows 7 to be pretty buggy. It blue screened on me any number of times and finally refused to load completely (despite trying every possible recovery option). Otherwise, it was great, very polished and a pleasure to use but I couldn't take the crashing and I'm now on Ubuntu. It's slightly rougher around the edges but otherwise works at least as well as W7 (and better in some areas).
