I use Linux~ and I haven't used Windows in about six months now XD So yeah...!

And I really dislike fanboys of either side of the Linux spectrum... both the "OMG LINUX IS PERFECT!!111" people and the "OMG LINUX SUCKS!!!1" people. All OS's have their strengths and weaknesses and you should use what works for you and makes you feel comfortable. I really enjoy using Linux, I find it to be very customizable and more intuitive than Windows, and the games that I play work on it, so I use it ^_^ But if you like something else better, then that's fine too~
