[citation][nom]evilaaron11[/nom]I don't think Steam for Linux will really change much of anything. Unless of course there are actually games to play. Regardless, however, the average consumer won't care to learn how to use Linux, so I doubt Windows is in any trouble at all.[/citation]Especially if you have to adapt the games for every major distro. Even then... what about cross platform compatibility? What about VAC? There's a lot more to keep track of now. I think they'd be better off sticking to just Mac/Windows, but it's their time and money.
