In my case, I'm learning Emacs after ~15 years avoiding it. I use a combination of Vim, Eclipse and Netbeans for enterprisey Java, but after that many years of a fixed mindset, I'm trying to reinvent myself and I'm trying both Clojure, JRuby and Git; Emacs has great modules to integrate them with ease. Currently I don't have the fluency I had with Vim but I think the effort will pay itself on the long run. The key is to practice and use Emacs as much as you can everyday.
