Ok. I know that is a little annoying, but I keep seeing fundamental misunderstandings around Flex pricing.
So, just to clarify, the Flex 2 SDK, which includes the Framework, compiler, debugger, docs, etc… will cost nothing. Nada, zilch… You ill be able to build and deploy Flex 2 apps using the framework for absolutely no cost (commercial, non-commercial, semi-commercial, etc…).
Btw, we will also have a completely free version of Flex Data Services (more on that in a seperate post).
So, if you want to start playing with the Flex Framework, then you can head over to labs, and download the beta for (you guessed it) free.
