Why not Flex?
butterfi: Why not HTML/CSS/JS?You can use it for web, widgets, iPhone/Android Apps. It's free, has a low barrier to entry, is easy to update, and has extensive documentation, both free and commercial.I'm not saying that Flex doesn't have it merits, but as a long time web/flash developer, I'm finding myself using Flash/Flex type stuff less and less (Thank You, JQuery!)
