Love it. Teachers who used them in school have said the same thing, gives you a feel for numbers. I bought a "Sun Hemmi" slide rule a few years ago. Ingenious devices and exquisite craftsmanship.

A colleague gave a similar reply to an English teacher who thought students don't need to know arithmetic, calculators do it all for you. She didn't know what to say.
