I've actually gotten Eclipse into a fairly clean state: http://i.imgur.com/ln2N8.png

Most of the clutter is gone, but all of the nice IDE features (refactoring, immediate error detection, etc.) are still there. It's a nice way to work.

I run VS2010 in a similar way, though it is much easier to strip off the widgets.

Most of my co-workers don't understand how I can work that way. I tell them it's all about learning (or modifying) keybindings.
