My guess is that they're already having enough legal issues with their pre-loaded software on windows. I don't know, but it seems to make sense that they're worried about another monopoly suit if they add the zune compatibility/main cpu software support to WM11.. Otherwise, I have no idea. I rip from wm11, then launch zune and synch.. it's a hassle, but not a huge one.. although it would be nice if I didn't have to re-do my playlists..
