I was left off the train that recently left for PDC 2008. Had I not gotten to go to Tech Ed this year I may even be really bummed. Lucky for me Microsoft has really made it easy to attend by bringing up the site microsoftpdc.com. The site has the entire PDC schedule listed and every (at least everyone that I have seen) session was recorded and viewable online. So far I have been impressed with the content that is out there. If you are serious about staying on top of technology, I highly suggest going to the site and checking out the content.
