This is not just about desktop and phone though. I ask my iPad apps to be as dense and powerful as my desktop apps. In particular, the screen sizes are mostly similar now, processing power is on the same ballpark, and if anything the iPad has more potential than the laptop from a design perspective. So macOS <-> iPad parity. Then there's no technical reason to not have iPhone <-> iPad parity. You end up with the chain desktop <-> iPad <-> iPhone
