The PDC Panels are great in that is has no prepared marketing dog food (no PPTs allowed). It is about Microsofties answering your technical questions. PDC bloggers will cover the various panels, and gives you even an opportunity to ask your questions before hand (even if you are not a PDC attendee).
I will be covering two panels :
Put The Power Inside: Hosting the CLR in Your Application - 10:30:00 AM - Room501ABC
Computing on the Beach: Visions of Mobility - 1:45 PM - Room 411-Theater
All panels are on the PDC's last day (Thursday Oct 30).
