The article only mentions Palm once, as author of the bestselling software on the Newton:
>Graffiti, a simplified handwriting system written by the company Palm, which would go on to make its own PDAs.
It doesn't mention GO Corp at all, which also made a handwriting recognition system, also not very successful.
People actually bought Palms and carried them around. It fit in your shirt pocket, in case you didn't routinely wear a jacket like John Sculley. You did have to learn Graffiti, but it was very simple with instructions that fit on a sticker on the back of the device.
