For technical (read that as math or science) writing the best choice is LaTeX. This software is a typesetting system that produces "camera ready copy" for publishing. (Ask your Windows friends how they use Word/Office to produce ligatures for fi, fl, ffl, etc.) One of the best TeX systems available is TeXShop on OS X using TeTeX. See: TeXShop: http://www.uoregon.edu/~koch/texshop/ TeTeX: http://www.rna.nl/ii.html I did a book in Word long ago - typesetting was a nightmare. I switched: My second book (and third and ...) was done with LaTeX -- I'll never go back.
