Microsoft has just unveiled SmartGlass, allowing you to use a phone or tablet to control content on your Xbox and get bonus content on that second display, but the company kept mum on its interaction with Windows 8 until just a minute ago. Microsoft has now revealed that, as expected, the feature will work with Windows 8 tablets and PCs. The company also teased cross-play between PCs and consoles. It's good news for PC owners — you won't be forced to buy into a Windows Phone or a tablet using Windows 8 to get in on the bonus interactivity offered by SmartGlass, you just need to upgrade your current PC to the new OS. You'll also be able to use the feature like Apple AirPlay or DLNA and push content you're watching on your tablet or PC to your Xbox 360 (and the TV it's connected to). It's not clear if this feature will make its way into a pre-release version of Windows 8 or not, but the company says that SmartGlass interactions will be in the "My Xbox" app sometime during the second half of this year. If you're not quite sure what SmartGlass can do (hint: there are some Game of Thrones bonus features!), be sure to check our report on Microsoft's demo of the service at E3 right here.
