WHere touch helps is with photos and 3D, I can use two fingers to rotate and pinch-zoom and then swipe over an object to select it for masking. Touch works very well for manipulating 3D objects in renders and more so in 3d CAD modeling. Touch works poorly for text.
I have a Microsoft "Surface" with Linux installed. Linux (See this:
https://elementary.io/ ) is much more Mac-like than Windows-like so I can claim "related experience". With my Linux/Surface, the best feature is that the keyboard can be removed. You need touch for that so you can type on-screen You have to use it for a while than touch become automatic when it works.
With my touch-enabled Mac-like notebook, for some kinds of work I'll can use touch with two hands, pencil in the left and multi-finger gestures witht eright hand. That works in apps that are VERY graphics-oriented. That said, my M2-pro Mac Mini woth 4K monitor is easier to use simply because of the screen size and resolution. But the tablet-like touch computer can be used while you are on your feet.
The touch tablet works like an iPad but has the capabilities of a complete desktop PC.
If I were an industrial engineer working os assembly line automation with robots and such I'd like to have a touch-mac. so A can work while walking around and mostly standing. Touch is good if you are not at a desk and many times iPad can't work because they don't use you Mac's same apps.
Don't worry about the price, all of those professions earn enough to pay for the high-end Mac with one job.
