I have a Windows laptop with touchscreen and pen support and I like it (HP Omnibook, Lunar Lake). My top use case is probably holding the hinge of the laptop in a way that one thumb can reach the screen, and I scroll with it. Revolutionary I know! Sometimes reaching up and tapping a button (large target) is faster than using the touchpad. Signing documents with the pen. A 360° hinge helps, too, for tent mode and everything in between. Touch is easier on an airplane when space is tight for my arms.

I can and do live without it on other devices (my desktop PC), but it's a nice addition that should just be standard equipment everywhere.
