I've been using TextMate for all of my development here at O'Reilly for about six months- and it's fit me perfectly everywhere else I use plain text. I wasn't a huge fan of the 1.0 release, but for some reason the 1.1 betas just clicked for me.

And I have no idea why, but text editors are a weird thing. They have to *feel* right and TextMate managed to pull that off.
