Adobe has decided that with the release of Gumbo (Flex 4) the Flex Builder IDE will bear the new name of Flash Builder. I personally think its a good idea - Its always been a but funny calling myself a Flash developer when I hardly ever open Flash nowadays. It will also clear up all the confusion on the Flex/Flash argument, God knows how tired I get trying to explain to people that Flash and FlexBuilder create the same thing, a SWF. Some folks seem to think that somehow or other a Flex SWF is somehow different or more grown up. Anyroad its a brilliant idea and long overdue.
