@Jeff Lewis: you're absolutely right.  The UI is almost exactly the same as Zune's.  I never bought anything off of the Zune UI.  In fact, I hate the blocky squareness of it.  I found it difficult to find what I was looking for and when I did click something it begged me for money (similar to Xbox Live?).  I hope Windows 8 just lets me use the apps I bought, like a new game, without having me peruse through apps they want me to buy.  The same thing goes for Windows Media Center.  Take me to the stuff I have, and the stuff I can get for free, then try to entice me to buy it in a non-intrusive manner.
