Microsoft’s wonderfully shiny new Xbox 360 dashboard is now available to most, and, while it’s a bit of a letdown in some ways (more on that later, probably), it has plenty of very, very cool new features. Cloud storage for game saves! New Netflix! HBOGO (Eventually!) One of the niftier features, however, is being saved solely for those rockin’ Windows Phone 7 phones. Called Xbox Companion, it allows you some degree of control over your 360 from your handset (as opposed to a standard controller), and it just went live.
