And to be clear, because people often muddy this, there's Flex the Framework and there's Flex the Compiler (or mxmlc, or the AS3 compiler, or whatever), and then there's the Flash IDE (and then there's Flex (Builder) the IDE). Simple, light applications can most certainly be built with Flex (as in Flex Builder or the Flex compiler, mxmlc), just make an AS3-only project. This would be identical to Flash CS3. The mxmlc compiler is a great option for those on a shoestring budget: it's free and doesn't require that you have Flash or Flex Builder. Troy.
