Since I first heard about the PDC I have always wanted to go, its the event which Microsoft uses to promote its business and provide developers and architects with information on how the tools they use will evolve. It is also held in Los Angeles, which is cool, imagine being sent to LA on work time!
The PDC is not a cheap event and I suspect unless you have a boss who is enlightened to how important this event is and work for a fortune 500 company you are very unlikely to be able to attend, although if you can convince your family to holiday in LA then I am sure its a good way to combine the two!
However do not fear for those of us with no holiday budget, other than a week in Skegness, and not working for fortune 500 you can still see every session at the PDC just by going to www.microsoftpdc.com.
I have spent the last couple of weeks listening to the video sessions, while working, and the videos are great most of them include a small picture of the presenter and the slide deck so nothing is loosed in not attending. The keynotes are the best videos, especially as if you had tried to attend the event yourself you would have had to content with looking over quite a few hundred people to get a glimpse of the stage.
