Xbox Live Update preview program so widely -- sure, all your stupid friends had the update, with their fancy new avatar clothing purchases and their cutesy little shared virtual Netflix screenings -- but there was you, updateless, sitting all alone, trying to squeeze out a few more experience points in Call of Duty while you held back the tears. Well, your wait is over. The newly improved Xbox 360 dashboard is live for everybody. Games on Demand, User Ratings, Avatar Awards... it's all there. Just ripe for the picking.
