Are we really talking about a typesetting system here ? I would not say
MS Paint is an order of magnitude better than emacs because you can draw
with pixel while in emacs you still have to draw in old ascii art.

Maxima, for exemple, being a symbolic expressions processor, will let
you work with symbolic expressions and provide export to latex formulas.
I have been using happily mixed session of auctex and maxima in the past
for scientific presentations. I guess imaxima has improved a lot since
and can provide most of what you will need nowaday.
