The next version of IntelliJ IDEA– 7.0.3 — will have built-in support for Flex development.
Among other things, it will support:
- Smart code completion for MXML and AS files, with cross-resolution of code symbols between them, even inside of mx:Script blocks and attribute values
- Automatic code formatting, highlighting and styling
- On-the-fly code validation with instant quick-fixes
- Search for perfomance bottlenecks, bad code practices

This is a great news for those who like to use IDEA as their preferred development environment. Also, it is good to have choice!
Price-wise they are at par — the personal edition of IDEA is USD 249, which is the same as Flex Builder.
