But even an half-way experience is an improvement for a feature that costs nearly zero dollars to include.

One of the most common actions among all computer users, zooming and centering a photo, is easier with a touch screen.

Even adding just that one thing is worth having a touch screen for.

Another example: working in the iOS simulator is now way easier because you can touch your apps that you're developing for iOS and iPadOS. And, by the way, macOS can run iOS/iPadOS apps directly from the App Store, so if there's something you really want to run that you just can't find a macOS equivalent for, there you go, you can just do it and interact with the app more naturally.
