I think you can also be quite productive in Emacs in a much shorter time. The difference is: the flexibility of IDEs stops after a while, and then there's nothing new to learn to become more efficient. With Emacs, you can keep on learning and optimizing your work environment. Disclaimer: I work with Eclipse almost exclusively these days, also because for Java it's so much better, IMHO.
