I don't care at all about a touchscreen macOS, I just want to be able to run the iOS Simulator on the laptop when I'm travelling and have touch like I would on an actual phone.
It's not like a touchscreen is great ergonomics on a conventional laptop but there are certain situations and applications where it's just convenient to have the option. And it's low cost these days, so it makes perfect sense to me for manufacturers to throw them in so you have the choice of a really easy, fast interaction when you're flipping pages or pausing videos.
What I really miss are pen digitizers which had been the basic minimum on convertible tablets for a long time in the '90s, but then everyone got rid of them. Only now they're slowly creeping back but mostly only on very high end tablets, although a few manufacturers like Lenovo have put them back on convertible laptops.
It's the portability of being able to do it directly on the laptop that I'm wanting.
And people who prefer computers should be very, very happy about that; because touchscreens on computers are stupid.
