Adobe added a new resource to help everyone including designers, web developers, programmers, managers and architects learn Flex the way they need to. It’s called http://www.adobe.com/devnet/flex/learn/. I can’t wait to dive in and make use of this. From what I’ve seen so far, it includes real-world examples, videos, links, white papers, articles, excercises, quick starts, and documentation.
Also be sure to check out Tour De Flex. It’s an AIR application that explores Flex capabilities and resources, including the core Flex components, Adobe AIR and data integration, as well as third-party components, effects, skins, and more.
