This year will be the 10th yearly VMworld event. (Have you registered for VMworld yet?) In the run up to the event, we’ll be running some features talking about the previous nine years of what I like to think of as the World’s Best (And Most Intense) Technology Conference.

One of the best parts of VMworld is the deep set of breakout sessions. Deeply knowledgable VMware employees, partners, and customers share their experiences in hundreds of sessions over the week. Some of us go to many sessions; some of us wait until afterwards, but the week is always filled with deep technical conversations during every waking hour. Although the conference is now very large and securely based in San Francisco, even in earlier years the conference team shared with us that it was hard to find locations to hold VMworld US and Europe because, unlike other events, we needed a venue with dozens of large breakout rooms!

So here’s the question – what’s been your favorite session or lab at VMworld over the years? Have any stuck in your head years later? And what makes it stand out in your mind? Was it the speaker, the new idea, or even the funny running commentary from your neighbor? Or was it how you had just the right answer when you got back to work and your boss thought you were a psychic genius? Or were you watching the right video presentation at the right time after the event? You can share stories about waiting in line or not getting the sessions you want, but those tend to be less fun.

Leave your story here in the comments and watch out for our series ont the VMworld Blog recapping the history of VMworld and getting ready for this 10th Annual VMworld 2013 in San Francisco where we will, once again, “Defy Convention.”
