All that stuff actually works decently well on mobile... as long as one is willing to accept certain compromises.

Note-taking works fine, in Google Keep, Apple Notes, or some other cloud equivalent. Yup, your data is in the cloud and owned by one of those tech megacorps, but most people just don't care.

Basic photo editing works okay too, in Google Photos, Apple Photos, etc. Ditto the cloud stuff.

What really makes most desktop users outliers is caring about, or even being aware at all of the concept of, actually owning your own data versus trusting cloud providers for everything.
