Adobe Flex

The Adobe RIA Flex technology is probably our favorite technology out there. It's mature, easy to use and it’s without a doubt the new level of web technology. Every new company that wants to stay ahead of the competition, and offers online services should aim to use it (or for the known competitor from Microsoft, the Silverlight).
