Smartglass, a free app that will eventually allow users to share content and control across multiple Microsoft devices, will be released on October 26th for Xbox 360. Versions for Windows 8 tablets, phones and PCs will follow over the coming weeks.
We'll be able to stream media content and browsing history between Windows 8 tablets, Windows Phone 8 handsets and Xbox 360 console... but as a gaming site, we're mostly interested in the emergent gaming applications that SmartGlass promises to offer. As an example, it's possible to access a dynamically-updating overworld map in Forza Horizon on a tablet or phone, and set up complex plays in various EA sports titles.
We could elaborate, but Microsoft have helpfully provided a cheerful software engineer to explain it all for us. You can check out the walkthrough above - and let us know what you make of it in the comments.
