PS3, internet play is FREE. It does a lot more then play games, you can browse the web, with a keyboard and mouse, transfer pictures off of a camera, video chat, print and of course watch blue ray movies. Blueray is the standard for HD movies so there will be lots more of them soon, plus, the PS3 is currently the cheapest blueray player out right now.

Also, me and a friend discovered you can use a usb PC controller with the same layout as the ps3's and it works just as well, and bout 30 bucks cheaper.
