Most of this discussion is focused around the benefits of having a TeX output
for math. And while this is perhaps the biggest place that we'd see a benefit,
it's by no means the only. This is also in part a response to comments that OO.o
should use MathML to hold mathmatical formula, because even if OO.o's *math*
rendering was equal to TeX's, I would still use LaTeX for any substantial
benefits due to other rendering quality issues. I'd just like to point out some
of these benefits.
(BTW, I'll usually just say TeX. The same applies to LaTeX.)
First, I uploaded an illustration of ligatures as an attachment. This was
constructed with a TeX file containing "fi {f}{i} \end". You'll notice in the
sefthand fi the "branch" of the f is extended to above the following letter,
where it takes the place of the dot over the i. The braces on the right fi force
TeX to break up the ligature. The letter sequence "ff" also causes a ligature.
In that case, the lefthand f has the same shape as it does in fi, and the branch
intersects the righthand f. ("fj" causes something essentially the same as the
"fi".) Compare both of the examples from TeX with what OO.o or Word gives you.
Second, the spacing in TeX output is, I think, noticeably better than a
traditional word processor. In a word processor, the MO for where to break a
line is "when I fill up the current line, I will wrap to the next one." But it's
possible to do better, and TeX does. The problem is that breaking one line just
when it fills up might force a latter line break to be much worse. When TeX is
laying out the words, it tests putting breaks between lines in several different
places. For each option it assigns a numerical "badness" value that rates the
quality of how it thinks it will look, then chooses the best option. The result
is a more balanced layout. TeX does the same thing with page breaks.
I'm sure I could come up with a few more examples if I did some investigation,
but I just wanted to illustrate the typesetting advantages of TeX beyond just
math layout. I hope that this provides a reason to support TeX rather than just
say "MathML will take care of everything."
