So my text messages will arrive twice as fast to the destination? Or phone calls will be two times shorter? Or I will read HN comment twice as fast while taking shit? Or the route found by Google Maps will have two times less traffic lights?

Nobody cares about how fast their phone cpu is. My iPhone 13 was significantly less performant than a top of the line modern Qualcomm CPU and never felt slow. Apple chips are also no more twice as fast as the competitions. The gap has been smaller for years.

If that’s all you have, you have basically nothing.

Only the experience matters and the iPhone UX is strictly inferior to the competition. Battery life is worse, camera is worse, screen is worse. So happy I switched and really regret ever trying buying one.

Additionally, Java and Kotlin are quite usable outside Android, instead of flourishing in a single vendor ecosystem.

Swift outside Apple ecosystem is as interesting as using Objective-C with GNUStep.
