Yes, calculators are made from plastic ^^

This throws up the question whether there are any calculators which *don't* have plastic keys. Maybe some NASA custom made space calculators with heat and UV resistant ceramic keys? Or heavy duty construction calculators with metal keys?

I've got a lot of unusual calculators in my collection and the only ones that don't have plastic (or rubber) keys are the Royal Digital III and IV. They don't have "keys" per se, instead they use gold plated PCB pads and a metal-tip stylus for entry. More about them here.

In addition I think that the very special keys on the Calcupen are made out of aluminum.
