A new update to My Xbox LIVE has added some new features to the iPad version of the app, allowing you to control your XBox Live account from your tablet:
• Use your iPad with your Xbox to connect, control and discover content on your console. Connect your iPad for access to a quick list of your most recent console activity. Control your content with play, pause, fast forward and rewind media controls. Find fresh entertainment to play in the new Discover section.
These tools have been available on the iPhone version since June, and have the handy ability of letting you control media without having to bust out your 360′s controller — which is great while watching movies and the like.
