I've found learning vim--either as a plugin for IntelliJ or Chrome or Firefox or as a minor mode in Emacs or by itself--probably the most productive thing I've done on a computer. I spend all my time editing code. It's incredibly useful to learn how to do that quickly. I went through trying to customise it perfectly but I found it is better--more portable for one thing--to learn its defaults. I enable a couple of things, like mkview and tabstop etc, but no more than 10 or 15 lines. My only criticism relates to the fact it's an editor, not an IDE; there's vimscript and I've made various vimscripts to give it IDE-like functionality, but the plugin system, and plugin systems, or lack of a in-build one, let it down. And it doesn't seem, unlike emacs, that is was designed with extensibility in mind. But as an editor: it's unparalleled.
