Xbox 360. I've got one, love it to death. never had a problem with it. As long as you get the cooling fan for the back, not a problem will come your way.
ALTHOUGH!!!!
If you play it sitting up on; like | instead of ___ DON"T TILT IT EVARRR!!! it scratches your CD and /gg video game.
Plus, 360 has Oblivion with HOURs AND HOURs of entertainment.
