You seem to be buying it all... lol And I use both my PS3 and 360. PS3 more because I like it better, but most of my online games are on Xbox to play with friends. AWell, its real simple. If a person buys both they just end up choosing one over the other anyway and the other is just a dust collector. Another thing is why buy a system just for a few extra games anyway. You can't have it all.
OH YEAH. I bought A Turtle Beach headset too!! woo-hoo.
