Yes. I have my dock/taskbar on the side and to switch between apps it's like having a small touchbar I actually know the functions of at any time. When I want to scroll too or tap quickly on something on the other side of the screen, it's often more worth to lift my fingers away from the keyboard to touch the screen without even moving the pointer. But if you're not used to it you probably don't see the burden of moving your pointer away to then bring it back to the center of the screen.

Another possible use is when I want to show some page or content to someone, I always prefer manipulating it with my fingers, instead of "remotely" control it from the trackpad and a mouse.

And if it has stylus support it's cool for drawing (like my current laptop) but Macs do not have a hinge suited for that I think (no 360° support and their focus on a "weak hinge" for the weird and useless obsession from tech content creators of being able to lift the hinge with one finger, something I actually not really value because I sometimes wish that the hinge was stronger and sometimes weaker).

Finally there are also multitouch apps like the piano shown on the presentation and iPad apps I guess, but on macOS I think this matters less (Mac apps are not made with this in mind at all, iPad apps are limited).
