Of course the text recognition system in the Newton (actually a trio of products working together under the hood: Rosetta, Mondello, and CalliGrapher) got to be good enough that many consider them to be among the best out there, even today. (And it's not hard to find traces of Rosetta even in modern macOS.) Newton folks were pretty good sports, and someone converted the "Eat Up Martha" Simpsons clip to display on later Newtons in 16 shade grayscale and it was pretty widely distributed, and the Doonesbury jibe about "Egg Freckles" ended up as an easter egg in the device itself.
