I'm a big fan of Ubuntu myself, and I think they're getting better and better at making hardware work with Linux distros. I also will try to develop my next game on linux, since it's just more fun. The only problem I see with Linux is that games don't often run on it, which is sad.

I convinced my girlfriend to install Ubuntu on her new laptop instead of windows and she really seems to like it, and even called it "simpler to learn" than windows. So for an average user, I'd really recommend it. Plus, if there's problems with hard/software, the community is by now so huge that it's usually very simple to get help.
