I have been hearing a bit about how Flex has capabilities that Flash doesn’t, however… As they both use the same flash player… It can’t be that big of a difference!
I guess I can see flex being better for launching large corporate applications and stuff like mapping tools.
Does anyone have a comparison chart of ones advantages over the other?
When I first looked at mxml I thought “OMG! XML flash applications. I thought you could just write applications dynamically and then run them in the .swf.” However, I don’t think thats possible…
I have no idea… I heart my Flash IDE.
