I've moved rather a lot since then, but somehow, and without any deliberate intention on my part, that calculator seems to have stuck with me...kind of like a cursed ring in an old Dungeons & Dragons game, with less eternal suffering and more calculating definite integrals. (Yes, it could do that.)
I found the calculator a few days back, while I was digging through a drawer looking for a roll of tape. It's been through a lot; it's covered with dust, and I have a hazy memory of spilling a shot of apple schnapps on it at some point in the past.
I flicked the power switch, not expecting a lot, and...it worked! The batteries, which have never been replaced and are now old enough to vote and drink alcohol, still worked a treat.
As powerful as modern smartphones and similar devices are, there's no chance they'll still work after a similar amount of time. Flash memory is cheap but transient, and loses information over time. Modern lithium ion batteries degrade over time. Leave an iPhone in a drawer for twenty years and it will be a paperweight on the other side.
This old calculator has a paltry amount of processing power compared even to a modern watch, but you gotta admire the way it just keeps going.
