I've been running Linux exclusively as my day-to-day desktop PC for a few years now. The rub being I don't game, or, well, I have one game I play (World of Goo) that plays just fine on Linux but I don't do the MMORPGs or anything like that. I've even got it on my netbook, and would put it on any laptop that I'd buy. I don't want to run Windows anymore if it's not absolutely necessary (and even then I'd try to run it as a virtual machine.)

Live the dream!
