Electronics wear out just like anything else. Cycling it on and off creates heat stress in connections at the very least. Mechanical switches are a week point they wear out from physical movement, seals at those points wear as well, and replacement parts after 30 years will be made out of Unobtainium . Even if the electronics survive, batteries can be a problem. I have a small collection of HP calculators that are at least 30 years old that would work perfectly except that batteries in the proper form factor are no longer manufactured. I recycled the plastic shells until they could no longer be re-assembled. After that it was easier to just buy a crappy new calculator. (Luckily when my original HP 42s crapped out, (keyboard failed), the replacement HP sent me used S76 cells, instead of the original PX13s...)
