The most exciting Xbox SmartGlass application isn't what you'd think

In Microsoft's ongoing battle to alter your association between "Xbox" and "Video Games," SmartGlass is its latest volley. Employing your favorite mobile device -- Windows Phone 7.5/8, Android, and iOS devices are all supported -- SmartGlass enables you to control your Dashboard experience, explore the web, input text, and much more. But what Microsoft's really banking on is its "second screen" functionality, essentially enabling another layer of interactivity with video, music, games, and the Xbox 360's other, less ballyhooed service: sports.

It's this final layer that I found most enticing during a recent hands-on meeting with Microsoft. Could sports be the "killer app" that MS needs to get SmartGlass out of its tiny niche and into the hands of the masses? I think so.
