Anyone else testing beta Xbox update? Mainly Internet Explorer.

Downloaded today and I'm very impressed with IE on Xbox. It's very fast and smooth, no lag or choppiness at all. The cursor is perfect. It also looks good and the controls feel natural.

No tabs yet and no flash. Is does have bookmarks, cookies, history. It also has the option to use mobile sites(unchecked by default).

As far as the Xbox UI looks, it's about the same but noticeably upgraded and more sleek looking. Also the kinect hand gestures can be used everywhere.
