Great Video! I hope Microsoft is on the right way. Most people don´t buy a OS because of a new networking stack (you can´t see a networking stack), they buy it because of a better look, a nicer style and design. That is something Apple has noticed a few years ago. I hope that Microsoft has noticed it now too. Of course it is not only the style that counts but Microsoft should has the capacities to do in both ranges (style and functionality) a good job.

PS: I find the Vista UI nice but not that exciting.

PPS: the PDC05 ribbons were great.
