A calculator is one of the victims of modern tech. Since everyone has a calculator on their phones, physical calculators are rare but they are nicer and faster to use than an onscreen calculator.

Schools still use and require calculators for tests. Hard buttons are nice. Limited, dedicated functionality is the goal. Dunno about rarity, they seem as popular as ever to me, and I feel like I'm in less of a Luddite bubble than some.

Still have my TI-84 and TI-89. Tactile interface works much better in the wild than fumbling on my iPhone.
