I won't bemoan free software and when Eclipse works it's great but boy howdy could it do with a Mozilla->Phoenix/Firefox style split where a lot of the things that are integrated into the base install (are there really people using things like Mylyn?) are removed, leaving just the bare IDE.
This was a big regression for me when the super-annoying Git plugin was bundled with Eclipse -- having to manually remove bundles from the installation directory is not a lot of fun nor a very robust method of plugin uninstallation. :(
EDIT: I will of course try this release, but I predict that I'll be sticking with IDEA.
Eclipse Platform and JDT runtime binaries do the trick here. Add-on must-have plugins as needed. Eclipse Standard has a whole bunch o' kitchen sink...
