You didn't quite explain what you want to say here. Questions that came to my mind when I read your comment: - Is the number of Vista/Linux users declining or increasing? - How long is Steam for Vista/Linux available? - How many games are available for Vista/Linux? My expectation is that Vista's falling, while Linux rises in that statistic. I'd say the fact that Steam is 'new' for Linux and relatively restricted/obscure for now (Ubuntu centric) the percentage isn't too bad. Given that a lot of games (mostly the oh-so-expensive so-called AAA titles in my experience) are still Windows only or Windows/OS X only, I find the number still quite interesting and not really disappointing.
