I remember hearing reports that it was initially having heat issues, but the massive amount of ventilation added to it was able to overcome. We\'ll see, there\'s nothing more irritating than heat issues causing crashes and problems. Again, a lesson learned from the Xbox.
As long as they made sure that form followed function, and there really are no issues with heat, then it\'s nice to have the PS built in, although I never really cared too much that the PS was separate on 360, it\'s something I could live with, but many others didn\'t like.
