“Like flying cars, people have been trying electric powered flight for a very long time”
Back in 1993, Apple released a product called the Newton, a small portable computer. It was supposed to manage your schedule, take notes, store contacts, and stuff like that. It worked, but not super well, it was cumbersome and expensive, and it got mocked for the poor functionality of its handwriting recognition feature. Apple stopped producing it in 1997.
And because the Newton was not a rousing success, Apple and everyone else gave up on portable computers and tablets. That’s why we all take our notes on paper today, and we flight plan on paper charts. That’s how it works out, right? We try something a few times, it doesn’t work, so we abandon it forever. That’s the way of technology.
