"We've done tons of user testing on this, and it turns out it doesn't work," Jobs said at the company's "Back to the Mac" event in 2010. "Touch surfaces don't want to be vertical. It gives great demo but after a short period of time, you start to fatigue and after an extended period of time, your arm wants to fall off," Jobs continued. "It doesn't work, it's ergonomically terrible."

Maybe users changed over the span of 16 years, while being daily exposed to touch screens? Remember, in 2010 the idea of using a finger was novel.

		Well my arms didn't get longer, that's for sure. Also MacOS and software made for MacOS doesn't optimize for touch targets unlike something that will be distributed on iOS/iPadOS.

		Not that novel. The first ergonomics studies on touchscreens were done in the seventies. In 2010, touchscreens were already sophisticated technology and well established in many settings. I got my first laptop with a digital pen and touchscreen in 2008 or so. They were rare back then, but nothing groundbreaking new. The touchscreen did suck though.

		It's not the finger, it's the arm. Remember light pens?

That was looking at it as a usability problem.

Now it's a "how will you still need an iPad" problem, that they have solved perfectly because it's a usability problem.
