BTW, if you are really wondering what PDC is going to be all about and not sure if my marketing bling (yeah right!) is convincing enough, you have got to check out the new show "Countdown to PDC2008".
Mike and Jennifer stick to the clock (analog buzzer!) and get it done in 10 minutes. No exceptions! Actually there are a series of videos on channel9 regarding PDC and you can view them all here https://channel9.msdn.com/tags/PDC08/
Truly any conference that Microsoft conducts is enormous and you'd be amazed at the amount of planning that goes on internally. I mean think about the fact that a geek like Mike Swanson's fulltime job now is to plan events like PDC!
BTW if you work for Microsoft, there is an internal countdown video series as well by Mike and Jennifer. Do check them out. Hold on, there is a lot of non-Microsoft people reading this post. Am I going off limits and crossing the corporate boundary out into the open clouds? Oh well, if my applications can do that, why not me ... Oops, I seem to have slipped a clue by accident.
