Apparently I’ve been a little out of touch. I’ve been happily using RDT with Eclipse and hadn’t needed to change. While catching up on some reading, I ran across this press release "Aptana to Merge RadRails and RDT into its Ajax-focused IDE".

Aptana bills itself as “the leading Interactive Development Environment (IDE) for Web 2.0 and Ajax development”. I took a moment and watched their screen cast and have to say it looks like a good start. As soon as I need to update my IDE again, I’ll look at switching over. For now, I’m going to keep pluging away with my current version.
