Big whoop. I have a touch-screen PC. I never use the touch screen. My guess is that nobody does except for a few special use-cases which would explain why Apple ditched the Touchbar. I also have a MPB with one and it looks cool but I rarely use it for anything that traditional keyboard buttons used to do.
We have three touchscreen PC's in our household, a Dell all-in-one desktop with a 27" screen, a Dell 15" laptop, and a Samsung Galaxy Book Flex Alpha 13.3" 2-in-1, primarily used by my husband. He never, ever uses the touchscreen on any of them. Even my kids, who are used to their iPads and iPhones (and touchscreen Chromebooks issued by their schools), when they very occasionally use the Dell desktop and Dell laptop, surprisingly never reach for the screen.
Weighing in on the original theme of this discussion, I have found that I can get absolutely everything done for my work on my combo of an 11" iPad Pro, Smart Keyboard Folio, and Apple Pencil. Granted, I know that not everybody can, but for my work purposes I can and I would love an iPad Pro with an even bigger 15" screen, paired with a Magic Keyboard and Apple Pencil. The combo has the perfect versatility I want, in that I never use a case with my iPad and I love being able to simply and quickly attach and un-attach the keyboard based on whether I want to get work done, or have some leisure time/entertainment. I actually just sold my 11" iPad Pro to purchase the (hopefully-soon-to-be-out) 12.9" with Magic Keyboard, and hopefully sometime in the future Apple will come out with a bigger iPad Pro which will be a day one purchase for me.
I bought my husband the Surface Pro (the biggest screen size, with the best specs), along with the keyboard and pen, and we both used it extensively for a few weeks (I really wanted to get a feel for it and give it a chance, see what it was like to use on a daily basis, although it was really for my husband). We both disliked it immensely. And my husband uses PC's regularly. As many people have said, it was not a good tablet when we used it in tablet mode, and not a good laptop in laptop mode, but a sort of compromise between the two. The touch interface was nowhere near as good and smooth as on the iPad; same goes when using the Surface Pen vs. Apple Pencil. My husband said the laptop/PC experience was far superior on his Samsung laptop; I felt the tablet experience was basically crap on the Surface and leaps and bounds better on the iPad. My husband would frequently just go back to using his Samsung laptop and I'd go back to my iPad Pro/keyboard/Pencil. Needless to say we returned the Surface Pro.
