Flex 3, AIR 1, and OpenSource
Wow, it's amazing to think about all of the wonderful work that Adobe put into getting Flex 3 and AIR 1 out the door. My congratulations to everyone involved. Lastly the source for the Flex compilers is open source, I've already thought of some things I want to try with that. Download, play, enjoy.
As a side note, I've updated my simple Window Explorer application to run on the released version of AIR.
