RPL2 runs on android? Octave/scilab and co run on android and windows, but on android they need a proper keyboard (not touchscreen that is pain).

The question about losing the device is a good one that I never seriously posed to myself. I remember my prof of the course where I learned how transistor worked (at physical level), that said "devices with integrated circuits either die quickly after the first months of usage, or last very long" and my experience seems to confirm this (it is different if there are a lot of capacitors, like in power supplies, motherboards, video cards).

So I always assumed in the back of my mind that the sharp el506w would last at least 30 years (so round about 2032) if I don't spill water on it and I hope the 50g would last until 2025 as well (I have a second model though and maybe I will get a third if the first two are too busy, I need to decide quickly though).

After that I guess I will rely on the Hp prime app and similar ones.

I love functioning tools (of whatever type, a very old bike, an old wrench, an old pump, a light bulb, etc...) and I find pitiful to throw them away (if I can I recycle them).
I have a tablet that died likely because the boot sectors of the storage got corrupted, still the RAM and the CPU in all probability are ok. I do not have the mean to recover and reuse them though. In my situation I need to be realistic. The same will happen with the calculators. Probably some parts of the calculators will be absolutely fine, but it is unlikely that I will be able to recover them.

Therefore: let them work now that they can.
