Definition of the most useless machine - doesn't fit in your pocket, has good specs but refuses to run anything not signed by Apple.. worst of both worlds.
To me this will be the kind of computers I'll tell my parents to use as soon as their crappy laptops die. They do not need literally anything else: sending emails, write a few ones, check Youtube and browse the web. For this use case, it's the most useful machine. Never breaks, infinite battery, no support needed.
And I hate Apple. So this says a lot.
I don’t have a use for the Pro model but I use my Air a lot.
Both are reasonable ways to make a decision.
It's a touch-first OS, for better and for worse. Anything else it was tacked onto a UI/UX made for a keyboard and mouse
