I
like it very much myself and I imagine the pro version Marcello

even better.  It may be that he just doesn't or won't like mathtype;

should definitely check it out first if he doesn't already know that 
he has it.
Zillions of equations created with mathtype can be found in my 
handouts at

There are **serious** problems with exchanging documents created by 
different versions of MathType / Eqn Editor, even on the same platform, 
all the more across platforms. Furthermore M$ Word and PowerPoint do 
not run on Linux/Unix. (Star*Office is a workalike, but M$ has probably 
put significant effort into getting them to break with the latest 
versions of M$ Office). Many of my Windows-using colleagues have been 
seriously bitten by this problem: they exchange a file created with one 
version of M$ Office for Windows with a coauthor using a different 
version of M$ Office for Windows, and when they get it back, the file 
is not recognized as containing equations--just un-editable embedded 
graphics. Solution: type all the flaming equations over again. Great 
for the grad students who get paid to do it; a huge waste of time. 
Totally avoided by using LaTeX in the first place: 20-year-old LaTeX 
code will compile today just fine. Try reading your M$ Word 1.05 file 
in Word XP.
Scientific Word/Workplace also has its down side: when it reads a LaTeX 
file, it translates it into an internal format, and does the reverse 
when saving it. The former step can choke, leaving you with a file that 
cannot be read. Of course the file can be attacked with a good old text 
editor and TeX'd; the TeX generated by SciWord includes a lot of 
extraneous junk, and occasionally it trips over itself.
Consider the Stata Journal article on IV and GMM by Baum, Schaffer, 
Stillman. We use different computing platforms, different OS, etc. but 
had no trouble collaborating through multiple revisions of a 
30-journal-page paper with a pile of embedded math. And when we were 
done, it was camera-ready for the Stata Journal. Most sensible journal 
and book publishers these days are happy to receive LaTeX manuscripts. 
Indeed, some recent econometrics texts have been typeset by the authors 
in LaTeX (no proofreading of the galleys!)
