TextWrangler is great for leftover Mac OS 9- users. We've had a modern operating system since 2001. People, get with the program. Abandon the Carbon software bloat. Embrace native Mac OS X software.

Vim is amazing. Textmate is still amazing (here's hoping 2.0 comes out sometime this coming decade). Subethaedit is incredible for its collaboration features. If you're editing and producing text files for Mac OS X, then learn the fundamentals of the operating system, and don't hide its Unix nature. If you want more than a text editor, use emacs. But vim is included with Mac OS X and it feature set blows away anything that Rich Siegel's company can come up with.

Carbon emissions should be banned!
