I use emacs, mostly, whatever version happens to be the latest in OS X or whatever debian distro I'm currently using. I don't make anywhere near as much use of the features as Gryph does, so version numbers don't really matter to me. If auto-fill-mode works as I expect, that's about all I ask.

For papers and other stuff that needs a little fancier formatting, I typically use TextEdit.app or AbiWord. I have a copy of Word, but I try to avoid it, especially for fiction writing. Just doesn't work that well.

Incidentally, I _do_ use blank lines between paragraphs, mainly because that's the easiest format for scripts to handle for auto-conversion and such.
