Best IDE for javascript server development [closed]

Question

After reading http://www.pragprog.com/magazines/2010-03/javascript-its-not-just-for-browsers-any-more I'm wondering which is the best IDE to develop server-side javascript applications?

I want a nice development environment with commonjs and node etc. Preferably windows but anything is interesting really. Is there any IDE with some nifty refactoring tools, maybe some intellisense-like function, etc etc.. Or is it notepad++ ftw?

I use Aptana 1.5 its very similar to eclipse which I use @ my work every day
