This is great. I've been waiting for a while to see some sort of good desktop UI that got away from the classic icons + sidebar widgets design. While this provides the same functionality, it gives the user a lot more information at a glance, plus it looks nicer (IMO).

I really hope that store becomes some sort of primary distribution channel. After using Linux for so long, I've become so used to repositories that it makes me cringe to go find some obscure nagware application when ever I need to get something done on Windows.
