360|Flex is the best conference to learn about Flex and AIR.  A non-profit conference run by my buddies Tom and John, is having its next round in San Jose, California.  Every time I have gone I have walked away with more good content then my notebook would hold.  If you are serious about Flex development (or even just getting started), you should attend.

If you need something to just sweeten the deal, I have a FREE TICKET to the event!  E-Mail me at nick@theFlexGroup.org for more information.  You might need to write a book report or something, but heck, it's worth the $480!  (BTW, this offer is only open to my UG members, sorry public internet!)
