One of the big selling points for Microsoft's latest Windows Phone 7 OS has been the interconnectivity between smartphones running the platform and their Xbox 360 game console. Word of the dedicated Xbox Companion app—which essentially turns your handset into a remote for the 360—came down the pike recently but Microsoft recently shot video of it in action at Nokia World 2011.

The app will launch services and control the Xbox Live Marketplace like video streaming straight from the phone but it'll also let you transport game elements from the WP7 device to the Xbox 360 and back again via a fancy QV code. If Microsoft can push this Kinectivity feature across first-party and third-party games the way they have with Kinect's features, it might just give people reason to go out and get WinPhone devices.
