I bought win 7 the other day and have some comments about how I would like it to work.
First: Internet tv through media center extender on 360 is missing.... why? It was in vista, why take it out?
Second: The windows media center desktop gadget should play videos in the small box instead of launching into media center. If I want full screen I'll double click it. The point of a gadget should be to catch the users attention, then preview, and finally watch if it is interesting.
Third: Why is there no xbox live gadget showing you when your friends are online and what games they are playing? Thats a simple concept. I would like to be reading news, email, or my favorite blogs, see a friend come online, and then go to my xbox and join a game. This should be a gadget available out of the box.
Other than that, everything works pretty well. Leaps and bounds over my experience with vista, however lacking these types of extra functionality really is a shame. It turns what could be a phenomenal experience into just a good experience.
