Tandy z-pda “zoomer” – from 1993.
You could on America Online, which had JUST hooked its network into the internet, allowing for newsgroups and internet email as well as its regular chat and forums.
I wanted it badly. It wouldn’t be until around 1998/99 that I could get a Handspring Visor, which had cartridge slots to add modems, network cards, MP3 players, even a camera.
Legend has it that a meeting with the Handspring people and Steve Jobs led him to switch directions at Apple towards a perfected Handspring, known now as iPhone, instead of his iMac direction which he was going in not very successfully.
