Adobe AIR (Flex 3.0)

Adobe AIR is a new runtime in development by Adobe and we are very close to releasing Adobe AIR 1.0. AIR allows you to write desktop software that runs on 3 operating systems (MAC,WIN,LINUX) with the same file. This allows your application to be a true desktop application rather then just a website and allows you to do much more than the web allows today. AIR applications are real native desktop applications and provide APIs for writing files, drag-drop, system notifications, network detection, and more. AIR empowers developers to write desktop software that leverages the Internet.

What is Flex ?

At the heart of Flex is the ability to create SWF files that run in Adobe Flash Player. Distill all the features down and really it is a development paradigm that compiles to SWF. It really is that simple but often we make the definition much harder. Just like Flash can create SWF files, so can Flex but the way you develop is completely different.
