I know I have had a lot of driver availabiltiy problems as well. It runs smooth otherwise. In the end, its going to be a resource hog. I don't think microsoft honestly is too worried about the memory usage. I didn't see a lot good reasons to upgrade though. It looks nice, has a couple of new kid games, and a new look for the media stuff. But there doesn't seem to be a good functional upgrade. Maybe I'm missing something.
