A friend of mine just recently notified me of this great reference doc. Adobe has released a poster style document for all their RIA platforms, Flex, Flash Player 9 and AIR.
It's comprehensive and is easy to read, you can download it here
I love these things and remember getting one when I first started learning Coldfusion. Turned out to be quite an invaluable resource, learnt more off that chart than I learned at University. And for that I thank you oh knowledgeable chart.
