When I got my hands on the book I campaigned in my department for
adopting it -- at least _experimentally_, in *one* group (I was at U.
Paris V at that time, teaching a Calculus course to Liberal Arts type
students). Colleagues were either indifferent or frankly *hostile* and
the argument the same as Harvey Friedman gave in a more sophisticated
form on the list: the students would have to learn epsilon-delta style
maths anyway and what could you prove with infinitesimals that you
couldn't with the standard methods.

The issue in Mac vs Windoze is more a question of money and marketing
