I've thoroughly enjoyed my time at the PDC this year, the biggest announcement was obviously the cloud services with the Windows Azure platform. But the greatest thing is the chance to network with other developers and Microsoft product team members.
This was my first PDC experience and I had high expectations, I think the conference overall was organised pretty well. But I have to say was disappointed that we don't get a nice show bag, was expecting some kind of nice backpack or laptop bag given the price of the conference ticket, but instead only got a plastic show bag
It would also be nice if the "Ask the experts" session was slightly better organised.
