I suspect most of the argument lies right here, and we're probably arguing
semantics and not real content.  I have always taken WYSIWYG as meaning
the manner in which the material is presented to the user, not the way it
is handled internally by the program.  Is this wrong?

Exactly... although I prefer "displayed to the reader" to "printed."

I think this may be the crux of the disagreement -- if there is one.  There
is a real difference in trying to get something to work on existing computers
and deciding on the preferred method in the abstract.  As an example, assume
you have available a Cray-class computer that is cheap ($499.95), and enough
backing ("I need a *big* tax write-off this year ...") to build your "dream
formatter."  Do you build a "dot-command" formatter or WYSIWYG?

Try to guess what computing power you'll have on your desk in 10 year's time.
(I've just been looking at a plug-in board that turns an IBM/PC into a
Vax 11/750 equivalent ...) THEN decide what kind of text manipulator you
would *really* like to be using right now ...
