sushila - Ken Henderson's session 316M was indeed worth attending, and since it was in the ballroom you'd have had no trouble getting a seat ;-) But yes it was darn hard at times to decide which sessions to attend. Ken's beta of "Nexus" looked cool, and it's now available on the Summit website so grab it while it's hot. He started off my saying that he had slides but that "they didn't really work". I'm pretty sure he intended to post them anyway. They're not there though.
Chris - nice summary. As for the tee-shirts - even when I stopped looking for free shirts they kept on being thrust at me! I did manage to get rid of the super-size REPLICATE that landed on me by going to the Microsoft boxes, but the idea of approaching someone with it and saying "you look like you'd fit this" didn't really appeal ... It's a sad state of affairs when you have to turn down free books and more, but as it was my bags were close to bursting when I packed. Thank goodness for the extremely generous weight-limits when travelling to and from the US.
Great Summit. Only a couple of the sessions I attended didn't really deliver on the description. Vineet Singh's "keynote" was wasted on marketing. He's obviously an extremely smart guy (anyone who can understand the internals of data mining has got to be) but anyone could have done that talk. At least Jim Gray didn't have to sell anything. Well, nothing with a specific brand anyway ... It will be interesting to see how SQL Server evolves to meet those challenges. Support for XML, web services and the CLR are early steps to the goal of "objectifying" everything.
