All you non-WP7 users don’t need to worry about missing out! SmartGlass will be able to link up your Widows Phone 7, iOS and Android smart devices to your Xbox 360! This interconnectivity between devices will be able to provide info on shows, be used as a remote, control the dashboard and more!
SmartGlass will also have in-game applications, like changing up tactics in Madden and another video shows a clip of Halo 4 being uninterrupted while sifting through online game invites. SmartGlass will be available Fall 2012
