My family spends two weeks with the Windows Vista Beta 2 version of Media Center in their den and comes away from the experience with some good and bad memories. First, the version of Media Center that ships with Windows Vista is a half-way house between the "old" (i.e. current) version of Media Center and a future version in which the UI will be completely overhauled. That is, in Media Center Vista, some bits of the UI have been switched over to the new style, but others--like the screens you see when you select a TV show, video, photo, or song--are still stuck back in a weird XP Media Center time machine.
