I'm evaluating it atm. If you know of something exactly like TextMate that is just a text editor (syntax highlighting), and not an "interfering code suggestion tool", I'd be interested.

Smultron, BBEdit, TextWrangler... depends on what you need, TextWrangler and Smultron are probably the simplest, although they're also limited in certain ways.

Hey thanks, TextWrangler looks much more promising than TextMate.

You might want to try Vim.
