Reminds me of what the messenger on the Cybiko was trying to be. Too bad LoRa wasn't a thing back then, it would have been more useful if it had a better range.
I remember seeing these on some tech show here in the UK - and being in love with the idea - seemed so cool and 'archivable' for a young person to own. A few years later they were dirt cheap on ebay - new/boxed, but by then the itch had gone, but I wish now I'd bought one.
Whoa, I wonder if I still have my Cybiko Xtreme somewhere.
