Not "verbal" as in spoken, though. This guy has some interesting ideas on how to improve calculators.
OK, maybe not laughable technology, but it's pretty zany nonetheless. The idea
is to make people enter numbers categorized by their magnitude. You type in "1"
"2" and hit the million key to signify the place to get "twelve million." You
add a few extra keys to your calculator and save a few keystrokes once in a
while. I thought RPN was bad enough...
