The PDC 05 Recordings are going to be made available on the MSFT web site for 6 months. This is 250 hours of your weekends and evenings that you have just lost, because you will be watching PDC goodness online. Sorry about that, but, not really. I'm looking forward to seeing those sessions that I de-prioritized while I was there, plannign for just such a day as when the recordings would be available. Check Michael Swanson's blog entry for all the details.
Update: they are now available! http://microsoft.sitestream.com/PDC05/
