My IDE is full screen emacs, with one emacs window running a shell for when I just want a command line. This works great on MacOSX and on Linux. It gives me integrated debugging, code navigation (with cscope-mode), code completion, git support and more. The downside is the steep learning curve, but I climbed that years ago and haven't looked back.

I have the same configuration... the only drawback is that its very difficult to do any real work on Java with emacs...

I'm guessing the main problem is the vast list of identifiers that you need to think about?
