When on your xbox360 and a call, text or other alert comes in on your phone...the alert shows up on the screen. Maybe even taking the call through your headset or even chat with the keypad accessory. This could be managed through the settings in case you don't like interupts during play. Just a cool idea being some people spend a whole lot of time on the xbox360 either playing games, chating with friends, watching netflix, listening to music...etc.
