Along with the sleek new interface the system includes customizable avatars, the ability to install all Xbox 360 games to your hard drive, a new mini interface when you hit the (x) button on your XBox 360 controller. It looks pretty very nice. Unfortunately I cannot test it for myself as my console is on its way back from red ring of death repairs as we speak. IGN did an excellent high def review of the new interface in these three videos.
