Your wording makes it sound like ARM is still being used just for smaller devices and controllers with very well defined and limited uses. General purpose computing is already possible with iPads and iPhones. They're just artificially limited by the OS. iDevices weren't really made with games in mind, but they can push out performance that beats handheld gaming devices. Artists (including myself) use iPads extensively and the response time with the Apple Pencil beats out just about anything else on the market. The only limiting factor is the tiny memory that limits the file size and layer limit on some programs. They're just fine for watching video, and even multitasking with a video playing while working on something else. This is on tiny device with no active cooling and long battery life, beating out most laptops in the same price range. I don't believe there is any curated use case. They're already more than capable of being general purpose computers. I mean, Apple is already openly advertising that they're making iPad OS more desktop-like and operable with mice and keyboards. Literally the only things holding them back are the OS and Apple's refusal to put some decent memory inside.
