Been running about a week or so with my new build and have gone with Ubuntu 12.04 LTS and so far I'm really digging it. And the install was easier than any windows install I've done. It just worked. Only a couple things I have found I can't do (or do easily atleast) that I might need windows for (netflix, and watching bluray), so may eventually install it dual boot style or perhaps run windows virtually on it. But for now I'm 100% Linux.
