For the Xbox users on here, Microsoft has released the SmartGlass App on Google play. Free! It allows you to use a smartphone/tablet to interact with the console - media, internet, games etc. The device support and gaming implementation looks premature right now but at E3 a while back they were showing SmartGlass implemented with Madden 13 and the Surface tablet (kind of like the Wii U experience). There is some potential here.

Installed it on my Samsung S2 and it won't connect to my 360.

Waiting for the next update.
