Sure, some people get a lot of use out of their laptop touch screens; but based on what I’ve experienced and observed, I surmise those are a minority. Who knows for sure though.I have two work Thinkpads, one company and the other client, and on my client TP I use both touch and trackpad for different types of things as you would expect from a hybrid device. Touch screen for general OS navigation and browser scrolling/navigation and trackpad and keyboard for application specific work. This is similar to how I use my iPad although I use the touchscreen more in apps because they are built primarily for touch unlike desktop apps. I don't use the touchscreen in applications more because the work-installed apps aren't built with touch-as-a-primary-input in mind. It's silly to believe that touchscreen would replace mouse/pointer control, it's just an additional form of control which you use for tasks which lend themselves to touch control.
PS. I get annoyed by my company TP without a touchscreen because I reflexively want to use it like my client TP which has a touchscreen. For the same reason I end up with fingerprints on my MBPs screen from reflexively trying to dismiss modals or launch an app from the dock.
Touch would have its usefulness as an additional way to interface even on a desktop OS vertical screen Mac, but in my opinion it’s just a “nice to have” in some situations—far from the necessity people who clamor for it for Mac make it out to be.
One sort of side note about the “reflexively touching the screen” argument though—I don’t believe that it’s evidence that touch is more intuitive than indirect pointing. Touch is more intuitive of course, but this isn’t the evidence for it that people think it is. Rather, it’s a result of learned behavior. The reason why we reflexively touch the screen is because we got used to it. That’s why we didn’t reflexively touch computer screens before the 2010s when touch devices became ubiquitous. In fact even in present day, after I’ve been using my Macbook and then I use my iPad with a keyboard but no trackpad, I reflexively touch the nonexistent trackpad. I do the same if I’ve been using a mouse, reaching for a nonexistent mouse. The reflex is mainly a result of muscle memory, not intuition.
