Guys, calm! He's chosen the xbox, totally his decision, he won't regret it I am sure, the xbox is a good peice of kit, and so id the ps3, it's matter of preference I suppose.
Just leave it, it's only going to end up turning into a flame war, and everyone getting pissed off, and getting banned.
(Ps3 > xbox)

Edit:
Can I just add one thing, people seem to be getting mixed up about?
Sure, the xbox has a marginally better gpu than the ps3, but the cpu makes up for it, the cpu outstrips the xbox's one, no question about it. What would you rather have? A few bricks with a few tiny details added, or a physics engine that blows your mind? Lets face it, the raw power of the cpu, can handle the physics so well, that it infact looks far better than the xbox.
