As a non-linux user, I'm curious: how many people have linux and only linux?
Because it's not, as far as I can tell, not packaged with computers the average person buys, but, I presume, used by more tech-savvy individuals (such as the average forum-goer here) would have linux in addition to windows/ OS:X, I figure especially so if they like to play recent-ish games.
I'd be more happy go lucky about this if steam hadn't turned to utter **** with the mac port and other major updates at the end of april (bloody thing wouldn't update to that new ****, now have noticeably lower FPS in CS:S when I tried showing it to a friend on midrange-for-laptop-range-laptop, even after doing some optimizing configs (and his laptop was better than mine, which was running it alright awhile back))
