I remember finally giving in to an invitation from a friend who back then worked for microsoft, to attend one of their launch parties. It was a big ass launch event in Brussels, and it was winter so I guess jan/feb 2000, for Windows 2000. Best food, best drinks, laser, a dj, ... really well done. The actual presentation told us how big of an impact this new OS would have on our lives. It would make us really happy, it would be so easy to communicate, ... and above all you could actually command your computer with your voice (which turned out to be a Lernout and Hauspie trick later on).

13 years later it's basically the same deal, but a bit more updated. I didn't see much about games in that video, but more about how to make your machine do stuff with weird gestures and how fast screens can swap. And of course that this machine will make man kind really happy.
