There wasn't much of a a perceived interest in gaming on the Mac and Linux platforms. The Mac and Linux graphics drivers were awful. A vicious cycle, which we're (hopefully) seeing start to break now.
Mac is supported by at least some major games, which is a step forward. The Steam box should speed things along nicely for Linux, hopefully.
As pjmlp points out, games were successfully ported to different consoles, it's just that Mac and Linux weren't seen as worthwhile targets.
I suspect porting a Windows game to PS3 would be much harder than porting to Mac, but developers managed.
