Smartglass is a new app specific for the Xbox, which does not require new equipment just your iOS and/or Android powered device, that adds to your Xbox experience. This app allows you to use your mobile device as remote, Keypad/Keyboard, and a second screen for gaming and movies so that you can get more info while you are playing a game (ex. in Halo 4 you can use Smartglass to locate ordnance drops, vehicles, and other things) or watching movies or TV shows (ex. in the Game of Thrones TV series while you watch Smartglass will show you a map of the country and where key points are and whats happening). I am really excited about this app cause its gives more depth to the games, movies, and TV shows. Now lets talk facts this app will launch coinciding with the Launch of the new Windows 8 this Friday Oct. 26th,. As for how much it will be, I am not sure, but I believe it will be free to get. So if you have an iOS, Windows, or Android powered device and you have an Xbox I would advise going for this app.
