SmartGlass can also turn your tablet into a controller. Microsoft showed a video demo of using SmartGlass on a tablet to play Madden NFL by designing plays and controlling your team.

The new SmartGlass app will be available for Windows 8 devices, Windows Phone, iOS, and Android devices.

Xbox As Entertainment Hub

Forget about Zune, Microsoft is turning Xbox into its all-in-one entertainment brand. Coming soon will be Xbox Music an online music service featuring more than 30 million tracks and available on Windows 8 PCs and tablets, Windows Phone, and Xbox 360. Microsoft also announced new video content partners for Xbox such as Paramount Pictures, Univision, and Machinima. The NHL and NBA online subscription streaming packages will be available on Xbox 360 for each sport's new season later this year. ESPN is also expanding its Xbox offerings with live programming from ESPN, ESPN 2, ESPN 3 and ESPN U.

Microsoft is also expanding the reach of the Xbox brand by including apps for Xbox games, video, music, and Xbox SmartGlass on Windows 8 tablets and PCs when the new OS launches, expected later in 2012.
