Being ATE (Ask the Experts) means that you cannot go each and every session you would like to. As a reminder for myself here is the list of sessions I made it to:
The only session to be rated "eminently forgettable" was DEV322. Well, at least I got to read my emails... The top-rated session definitely was Bob Beauchemin's SQL402, which kind of was an interesting session to go to before ARC304. Great fun was Rob Miles' XNA talk (this session doesn't fit the pattern of my interest, does it?).
There are a couple of sessions I missed, but I'll watch those once the post-conference DVDs have landed.
