Casio Cassiopeia

Casio Cassiopeia was the brand name of a PDA manufactured by Casio. It used Windows CE as the Operating system.

Casio always advertised the fact that their devices could be updated. Casio decided it would not issue an update for the E-100 and E-105, and a lot of owners of the devices complained. Because of the complaints, Casio offered to update the devices to the newest version of the Operating system if the owners sent in the device and paid a fee. Since the operating system was stored in ROM and not flash memory, the only way to upgrade was by replacing the ROM.

gollark: Equal/better how? I don't know about pen-capable ones, but there are some very cool developments nowadays with graph-structured note-taking applications. I am, very slowly, making one.
gollark: I mean, there's no search, backups are hard, you can't conveniently include nicely rendered diagrams, there are no links, you have to write text with a pen, storage actually costs non-negligible quantities of money.
gollark: Pen and paper are really quite bad.
gollark: There was in fact quite a long time before the cloud things of today, and people didn't (have to) just lose data constantly.
gollark: Or, well, unencrypted cloud things.
