I ran into this thing someone built and is releasing kits for. It won't be near as smooth as PalmOS, but if you're into hacking a little bit, it might be worth looking at.

I've seen some other people hack together similarly devices. One was a Raspberry Pi 0 with a blackberry keyboard and a screen.

Anything off the shelf and even remotely polished these days is likely running Android, which seems like it would defeat the purpose.

The are Remarkable Move might be an option, if you're looking more for a notebook to organize everything, but if you want a Palm-like experience, that will also miss the mark.

You could try for an old Palm or Handspring device off eBay. It might be its own island, or getting in syncing could be a project.

You can run old Palm ROMS on smartphones. I tried it, but once the nostalgia wore off in 5 minutes I gave up on it. It also seems to defeat the purpose of what you're going for.
