Not really the PDC, just the Pre-Conf sessions. I've chosen .Net Data Access from A to Z. By now, it's just a quick recap of Data Access technologies from the last years, how long from last time I hear someone talking about RDO or DAO...

The session is getting more interesting, now we have started to see the Entity Framework with Michael Pizzo, this guy knows  how to make a demo, he is adding more relationship as attendees ask for it !! cool...
