Thanks, I read emacs-devel thru gmane, so cc'ing is faster.

I'll try to write up a list of the features and post it with some commentary.

Regarding the Carbon-AppKit port and its predecessor the Carbon port,
it and the Cocoa port have become more similar from a user perspective
over time, as each derived inspiration from the other and feedback
from a shared user community.  There is some greater difference under
the hood, since one developed to the object-oriented framework from
the start, but I think that is becoming somewhat less now with
Carbon-AppKit (I've not seen all the code there), and my own efforts
to make things more uniform with other ports.

The Cocoa port supports a superset of the platforms (due to GNUstep
support), but the Carbon port, despite being younger, is more mature
and robust, so as long as people are working on it (now on
Carbon-AppKit), that's another good reason to keep it.
