Best text-editor ever, and no, I don’t want to play the “best editor” war. ;)
One thing I’m sure is that it’s the best €39 I ever spent and v2 will be a free upgrade (it will require Leopard, BTW. Not a problem for me.)
Besides the normal code and prose writing, I use it for almost everything thanks to the “mate” command, the “Edit in TexMate” input manager, the blogging bundle, etc.
