Apple is a still computer company, because Phones ARE computers. For the majority of the population in developed countries, and almost all of the population of developing countries, smartphones are the only computer people have or need. I agree that Apple have shifted focus away from "making tools for people to create things and solve problems" towards consumption-oriented mobile devices. But those devices are still…
Wholly agree with you -- in fact I think we're at a turning point in smartphones catching up to being full fledged computers. I've written some thoughts about this previously, if you would care for a detailed elaboration: https://guan.sg/apples-2017/
I'm skeptical that this will work for everyone.
Everything is tradeoffs. When "must be tiny" is the top priority, performance and battery life necessarily suffer.
There will always be people - from gamers to video producers - whose top priority is performance. And for computer geeks generally, the weight difference between a laptop and a phone is not compelling, but having four times as many cores would be.
The portability difference between a mainframe and a laptop is immense - it changes your working life. The portability difference between a laptop and a phone is much smaller. It means you can do things spontaneously, because you can always have the phone with you. But if you're planning to work, the difference is minimal. Especially if the smaller form factor means you have to plan to have peripherals wherever you're going.
Eg, I can take my laptop to a cafe or a park and work. I couldn't do that with an "ultraportable" unless I bring my own peripherals. So it's actually less portable for the situations I care about.
