>> we have better programs for dealing mathematical notation Not that I know of, no. The fastest thing available is LaTeX, and you need to compile to see if the formula came out correctly or not, and you might not know how to encode some of the gnarlier formulas or characters. And even if you compile as you type, it's still not as fast as writing by hand. You can write formulae by hand using a digitizer, but the experience leaves much to be desired as well.
