The Eclipse plugins are getting very good which is dragging me away from IDEA (who's plugins mostly suck).
The WebTools project is good - very useful for editing WSDLs/XSDs. BIRT looks awesome. The AspectJ plugin impressive. The Spring plugin
is handy.
Also IDEA 5.0 breaks the 'maven idea' plugin too which makes
moving back to Eclipse even more tempting. I do love IDEA for hacking
Java code; I'd love it if someone refactored IDEA to be the Java editor
in Eclipse :)
Maybe someone needs to do an IDEA key-bindings for Eclipse? (I've made
a trivial start - splat-D for Text editing -> Duplicate lines).
