Sticking a keyboard on an iPad does not a laptop make. Being limited to mobile app versions of web browsers is itself a big enough quality-of-life downgrade to make the setup much less convenient than a laptop for leisure-time media consumption, not to mention professional work.

Sticking a touchscreen on a laptop does not a tablet make.

GP wants a laptop with a touchscreen, not a tablet. My laptop has a touchscreen. It's not the primary input method, but it is quite handy sometimes.

I'm not really interested in a touchscreen on a laptop, but I'd buy a Pencil immediately if it worked on my Mac screen.

In what way?

I would instantly go for an iPad Pro, if it would run normal macOS. Or things like vscode and docker, and games. I just can’t justify to myself the expense compared to an m1 laptop, just for the form factor.

unfortunately the ipad os is the limitation on the pro. I tried to make it work but its back to its previous position as media consumption, music production box (which is annoying to deal with due to lack of audio outs), and occasional text editor.

Sure the iPad has its down sides. But it also does complicated things dummy easy. Example tossing a pixelated/blurred box onto a video. That's ridiculously complicated on windows and requires a hell of a steep learning curve. No problem if you have the time. But a blocker if time is and your video editing skillsets are short.

Your example is one enabled by the application, not by the platform. You can find easier video editors on windows or on android as well.
