What I think would satisfy a lot of users is if an iPad (And even an iPhone!) turned into a full-on Mac with full macOS with a keyboard and pointer attached. No need to create a convoluted hybrid touch+pointer UX that wouldn't be great at either, like Microsoft has proven. I simply want to be able to do more with the hardware I already own, and transfer files between my mobile/content consumption modes and when I'm creating/developing/working on something.
I know Apple just wants to sell more hardware, but what's happened instead is I've lost interest in getting an iPad altogether.
