I've got no game console and to be honest, I'm not that interested.

PC is the most flexible platform of them all. A good gaming PC generally has better hardware than most of the consoles today (Allthough the PS3 will out-perform most of 'em).
Also, I'm not much of a gamer. I'm more of a tech guy who likes to mess around, so there's no point in buying an expensive console. I don't even own a TV to connect it to, nor do I have room for one.
