Syntax highlighting, code completion, jump to definition and code linting, search and replace (regexps) in project... and of course a nice and, most importantly, fast code editor.

So, I use Sublime Text. Although it technically isn't an IDE, with some plugins installed (SublimeCodeIntel, SublimeLinter, and others), it works wonderfully as is if was. And it's blazing fast too.
