Honestly, all you need is notepad++ for the fancy tab stuff and the automated closing braces, everything else is just a fun toy.

I bet most people don't use 1/10 of the IDE's full capabilities. I myself only benefit from Code Assist, Syntax coloring, tab sync, WYSIWYG previews, tabbed interface, and automatic refactoring. I mostly blow the money just because I like to have shiny toys.
