The PDC site is full of announcements (and there will be more in the days to come, based on some emails I've received) so there are even more reasons to attend than before. The number one reason to come to PDC is to LEARN. Well some topics just don't fit into 75 minutes, and attending 3 different 75 minutes sessions by 3 different speakers who may or may not have co-ordinated their coverage is a strategy that might work if you're lucky, but might not work either. Enter the PDC Symposia - co-ordinated coverage of the two MUST LEARN topics this year - concurrency and cloud computing. Don't worry, you don't pay any extra or anything, just choose to attend these sessions on the last day.
The second reason to go to the PDC is to GET THE BITS. PDC has always been the place to get the fresh-out-of-source-control latest build of something that won't see beta for a long time yet. It's already been announced that those bits will include Windows 7 and will come on an external drive, not a big stack of DVDs. Cool!
The third reason to go to the PDC is to MEET PEOPLE. An utterly astonishing array of executives and wonder-brains are giving the keynotes. As well, the speakers are essentially all internal Microsoft people who've been working to create the technologies they're showing you. And the attendees are a cross section of developers and architects who really care about staying ahead of the curve and learning what's coming before it comes. A single lunch with any of these folks could change your life, or at least your job.
Register while you can! And if you see me there, say hi!
