My mother purchased a handheld Sharp calculator in 1971 that cost about $600. My grandmother (a schoolteacher at the time) brought my mother’s calculator to class to show around, pointing out they would eventually be super-cheap and replace the slide rule.
A parent complained about her telling lies to her kid, and she was admonished a few days later by the school administration.
I actually own a slide rule, basically the prepper in me which says I need to have a calculation device not dependent on electronics. I’m on the lookout for a nice abacus too.
