Imagine being isolated off-grid for an unknown number of years. Maybe you're stuck somewhere like Davidge or Mark Watney; or perhaps you've chosen a life of isolation like Yoda or Obi-Wan Kenobi. Maybe you're a survivor of the $Apocalypse. Wouldn't keeping a journal be a great idea? You could pass on your knowledge, keep track of daily activities, maybe even keep yourself from going insane!
Forget all the wastefulness, extravagance, and complexity of most modern devices, you've got survival to think about! Obviously power usage would be a major concern, but ergonomics, searchability, repairability, and data robustness would be important too. Keeping in mind that this is a dedicated device for journaling and barring the old Russian pencil and paper, what would the best solution look like with off-the-shelf modern technology?

Honestly, if you want a solid computer you're looking for 80's/90's stuff that lasts for decades. Some of that stuff was running up until it was tossed in a dumpster. I'm thinking m68k, EEPROMs, flash, drams and srams with a mono lcd.

Yeah, that's still not going to survive if you trip and smash the thing against a rock though, so you'd likely still want at least one spare...and with size/weight considerations you might be better off with a redundant array of garbage SBCs compared to a single ancient but robust luggable. Depends on the constraints...if weight matters but cost doesn't, buy two dozen Pis and two hundred micro SD cards and call it a day. If cost matters but weight doesn't, buy as many ancient PCs as you can. Although you may also need to consider how you get your data back out, too...you could eat up a good chunk of your budget on interface adapters if you're buying older hardware.

If SD cards are so awful, why do I hear that SSDs are pretty good now? They've maybe pulled ahead of HDDs in reliability.

Maybe because SD cards aren't SSDs? Aside from the underlying bit-storage technology they're completely different products.
You may as well ask: If floppy disks are so bad, why do I hear that hard drives are pretty good now?

No grid.
What you going to plug those energy sucking old pigs into? A Current Bush.
No, you are mistaken. I've always had this sig.

hmmm. Now you got me thinking. If it were a divine burning bush, one could build a boiler around it and...

If we're starting from an assumption that you can have a computer system that will survive whatever duration is required in whatever environment it's required for, then surely you could also have a sufficient quantity of solar panels (plus the requisite redundant backups).
But that does make the old machines look even worse compared to a big bucket of RPis if you've got any constraints on size or cost...
