I'm a lawyer by trade and am forced to lean on GUIs with little keyboard-control support. When I code (for pleasure), I don't miss the touchscreen, but I often miss it when I'm trying to read PDFs and Word documents on the go.
On Macbooks the trackpad is so large that you can reach it even from the sides of the laptop and the two finger scrolling actually works without second thought.
I don't really expect anyone to use it as a touchscreen, but if they do, at least that will work too.
There's a lot of small niceties that pile up into a better experience, the sister comments cover a bunch of those, so I'll focus on a macos specific nice point:
iPad and iPhone apps can now get direct touch when running on a laptop, instead of the mouse mode. With this, there is now a perfect platform able to run Mac, iOS and iPad apps outside of the ill-fated Vision Pro.
That's too little to late for me, but I think many will appreciate the benefits.
I mean just imagine how jarring it is to go from touching the macbook screen to mess with your app to needing to input text. Whether you use the macbook keyboard, or the on screen keyboard, it's just kinda rough.
The only situation I could see it being useful in is if it came with a pressure-sensitive pen, so you could use it for sketching and drawing. But even then, that would only really work well if the screen folded all the way around, so it would sit flush against the base or if it opened 180 degrees, so you could lay it flat on a table without it wobbling around on a hinge.
Maybe the the intuitive and natural way of interaction is touch and the generations between the boomers and the Gen Z are the only ones who command the skillset to use computers in any other way.
Seems like it would be useful for app development being able to do touchscreen for the iOS and iPadOS simulators.
Even now, I find myself resisting the urge to tap things on my Macbook display as it is.
The world moved on. Touch is standard, and Steve Jobs was incredibly wrong with his weird opinions.
This is like people arguing that a computer mouse is not necessary in 1990.
