Solid. Native Carbon port of Emacs 21.1 to OSX. It may not be native XEmacs, but it beats using XEmacs in XDarwin, as I had been doing. You can download a build now from http://www.porkrind.org/emacs/index.html courtesy of david@porkrind.com. It's based off of Andrew Choi's magnificent work to get Mac OS and OSX patches into the main Emacs tree; this is just a handy prebuilt binary until an official one is put up. (Thanks to Rainer Joswig for finding this.)
