Let me start with this. My initial reaction from the first iPad still holds.
Why not touch macOS? There is just one answer: Profit. The business is not in solving user problems. It is to create a shiny toy with a limitation which you promise to solve in the near future. I moved away from iPad for drawing and just use it for a second screen on the go. For mobility, I have a smartphone.
It is getting ridiculous in an Apple camp. You introduce the last processor on a iPad? But iPad still is not a full laptop or desktop replacement?
Why?
