I remember that reference and use it often when discussing the modern PDA and smart phone. It is the first reference I remember for the device that everyone uses now, but then it was really science fiction.
I do not recall authors like H Beam Piper using hand held computers at all in their stories. Though James Blish did mention a "cat's brain computer" in the screenplay short story adaptation of the Star Trek episode "Miri" published in the early 70's. However that was the size of a modern desktop printer.
In the old ST Classic episodes, books were read on moniitors rather than hand held devices
The Star Trek Padd was used to read books in STTNG, but that was much later on.
