In a time where every constraint was extremely limiting (batteries, storage, cpu / SoCs, IO, displays) there were many interesting approaches to hardware and software designs for ultraportable computing.

Almost very PDA in the market had a fairly distinct OS -- or at least custom "spins", not unlike android today with manufacturer customizations.

I owned (and loved) several palm OS based devices, but I always looked at the folding "tiny laptop" form factor of the Psion series (and the Zaurus) with major nerd envy.

Personally I think the refusal to move past passive-matrix 640x240 screens seriously impaired them. Even as late as 2005, NEC was marketing thousand-dollar MobilePro palmtops with the same dogshit DSTN LCD from 1998's Jornada 680.

The one I had and loved was the HP Palmtop - tuning the "obscure OS" known as MS-DOS 5.0

You could beef them out pretty strong
