re: "I hear comments from dozens of people that tell me they'd
consider M if it were much cheaper, like another math tool with much larger
distribution that people use"

If you mean the other math tool I'm thinking of, then to a certain
extent it is an apples and oranges comparison. The math tool I am
thinking of might be cheaper to buy but to actually do anything useful
you need many toolboxes which can raise the total cost to double or
triple the M cost.
