Every time I've tried linux there has been multiple reasons for me to say "Okay, back to windows." It's not a worthwhile system for most people, no matter what anyone may want to believe.

This is why people hate the US.
All games have to be played online. There won't be single player games anymore, there'll just be web based games or virtual worlds you can play single player-style or massively multiplayer style, but in either case the data for the game world will only be on the server.
That point is when I will stop playing games all together. I can't stand playing games online most of the time, especially FPS games. If there's no chance to play a game by myself, without the interaction with another player, then there's no possible way the game will be good enough to warrant my attention.
