I liked the videos that Microsoft shows at conferences. You can tell they put a lot into them. I was lucky enough to see the 'Behind the Technology' video at PDC. That was pretty dang cool. Though it seems that I missed another cool one showing Microsoft and the Matrix. Ballmer is Neo and Gates is offering him the BIG BLUE pill or the Red pill so that he can continue to stay in Wonderland. hehe. If you find where the video can be downloaded on the Internet, post a link here please.
UPDATE: Jason Olson found a link that has part of the video. You can get it here.
