When you build applications in Flex Builder, you’re building them with the open source Flex Framework and ActionScript. The applications then get compiled in to a SWF-file that runs in the Flash Player. When talking to customers, I regularly got asked if you needed “Flex Player” installed to run an application and that is exactly the type of confusion that we want to solve. By renaming Flex Builder to Flash Builder, there is no doubt what you are going to build using this product. You’re going to build an application that will run on the ubiquitous and trusted Flash Player.
同时，更兴奋的是Flash Builder 4（现在应该这么称呼了）和Flash Catalyst（就是原来的Thermo）将在今年夏天发布公共Beta测试。
