Ever had hassle with your numerous Eclipse plugins? With update-manager complaining about missing dependencies, which nobody ever could resolve?
With re-installing your (free) development environment every now and then?
After giving the latest Eclipse ("Galileo") a try, I just dumped it: After configuring Spring, Scala, webservice, subversion and a few other plugins, the whole app did not even bother to start...
Having been Eclipse user for several years, I am really grateful for their contribution to (Java) software development. But it has become an overly complex monster in my (humble) opinion.
I lighthearted moved over to IntelliJ-IDEA - their slogan "develop with pleasure" became true within the first hour of using IDEA (I tried both 8.1.3 and their early-access version 9). Grails and Groovy support is excellent, Scala plugin working fine, subversion support the best I ever had, even Clojure working (ok - that one can definitely be improved, but true lisp programmers should stick to Emacs)
