It may sound like a bash against the 360, but I really don't care. The fact that these games are going to the PC is probably one of the biggest reasons that I don't want a 360. My PC is like my hub of games and work so I'd rather upgrade it and get games that are coming out for it (even if I have to turn down some graphical effects) rather than go out an buy a 360 and get the games that would most likely come to the PC anyway.
The other big reason I don't want a 360 is because of Live. The saying "You get what you pay for" will (most likely) never set in with me because with PC gaming and things like Steam, I'm already getting all of these features for free and I think Xbox Live (which requires you to pay to play online) and Windows Live (which heavily gimps you until you pay) are a large ripoff in my opinion. The only 'advantage' is that if you have your PC and a 360, you only have to pay for one subscription.
Of course, another reason reason is that I know people that own a 360. Hell, I can walk three steps out of my room and there are two 360's (core and premium) sitting right next to the TV
