Actually in my opinion yea the blue ray and the built in wifi. other than that, the 360 beats the ps3 in functionality and ease of use.
I know I know. ps3 fans will be mad about this statement... I own both systems and i gotta say ps3 totally screwed up with the networking or online stuff.
once you use the 360 online there's no going back its just soooooo simple to use. but the 360 doesnt have blue ray or wireless internet built in. so yea the ps3 is a better movie player. and the controllers are waaayayyy better feeling than the bulky out of shape 360 controller. lol
