Funny and informative "Lap Around Longhorn" video from MSDN TV
Yeah, I'm trying not to be too excited about something that we'll see in only a couple of years, but you really have to take a look at Don and Chris's MSDN TV show, where they recreate the presentation they made at the PDC (actually the PDC is a recreation of this show):
Some really freaky stuff in there (not to mention some hilarious moments). It's so cool I had to stop midway and let y'all know about it. In fact, I think I'm going to continue watching this with a big bowl of popcorn :)
