How can it be done?
Sandproof, waterproof, sunlight readable, all-day battery powered computing device wanted with sufficient power for compiling stuff.
Bonus points if it has an ice-maker.
Does it exist? What's the closest?
I live in a coastal community and literally the crews had these things on the beach, a couple of times dropped in the shallows and picked back up and still fully functional. Those machines are insane. Had one medic drop one in a horse trough full of water, he literally called me and was worried about picking it up out of the water. I told him pick it up, dry it off and let me know if he was good, he did and used the computer the rest of his shift.
One drawback is they typically aren't the latest CPU or the fastest machines but they were always solid. I haven't used one in years but I would venture to bet they are still the same way.
It is a fairly decent ebook reader, with decent PDF support, stylus and a nice note-taking app.
The interesting thing is, it has bluetooth-support and runs Android 6 (heavily modified, it still is a reader-first) but you can run Termux on it.
I ran into some problems with 32bit processor it runs and it isn't the fastest, but I was able to do some i.e. Rust excercises :-)
It even has blue-tooth, so you can hookup a real keyboard to it.
