Favorite code editor and why?

mconway and I were talking and it made me want to ask: What's your favorite code editor and why?

I really like Dreamweaver for its clean look and helpful commands, but I can't afford it at home. For a while I was using Crimson Editor and then PSPad, and recent started using Eclipse, but it lacks some of the simple features Dreamweaver does.

So, what's your favorite code editor and why?
