So day 2 here at Nokia World and we got to play around with the Xbox 360 Companion App for Windows Phone 7, featured here on a Nokia Lumia 710. The app is planned for "this winter" which is a little later than we were hoping and it also means what you're watching is still in beta.
Having said that it's pretty freakin' sweet. Think of it as an augmented remote. Sure it an control the Xbox for media, selecting movies and even using a virutal D-pad. But more importantly, it pulls down data about shows or moves you're watching, gives you general information and allows you to browse on the phone instead of the Xbox itself.
While not hologram material, it's certainly headed down the right road by providing deeper integration between the Xbox and Windows Phone and we know we'll be itching to get our hands on this ASAP.
