The user interface has been revamped to support multi-touch gestures, though overall the organization and layout is mostly the same. Some noticeable changes include an updated store stocked with new HD movies, rentals, and TV shows as well as an optimized Zune HD browser that fully takes advantage of multi touch.
Interestingly, Microsoft also revealed plans to position its Zune HD device as a mobile gaming platform. Later this year, in addition to releasing free applications such as Twitter and Facebook for Zune, the company plans to offer 3D games such as Project Gotham Racing: Ferrari Edition, Vans Sk8: Pool Service, and Audiosurf Tilt.
