I just got it and so far I'm liking it. A lot cleaner and snappier.

The new Netflix is cool too.

ESPN was the thing I was looking forward to the most and it is awesome. Will be even more awesome when Time Warner's new contract goes into effect so I can access everything.

The Zune music integration would be great if you had a Zune pass. I might think about resubscribing for a month or so to see how much I use it.

i havent been online in a while, i'll have to check it out. the last version sucked i think. even after a year or whatever it was, i still couldnt find my way through those menus.

It isn't out yet for most people. It's still in beta.
