Earlier quoted context omitted.
It’s true that before Apple Silicon one could make the argument that the hardware benefits of a Mac were mostly incremental vs a PC. But today that’s not true anymore. Today Apple is both form and function. I’ve personally heard many misguided people still repeating blindly that Apple is “just” fancy design without having used Apple Silicon computer.
Apple computers (unlike their tablet or phones) are saved by extremely good Devs who managed to implement a very good package versions control, brew, and a lot of external software (non-webkit browser being the biggest) make the computer actually good. I think Apple native package version control is worse than IIS pre-version 7, and that's saying something (maybe it's better now, but that used to be the worse).
Apple computers now use more or less the same architecture as their phones, based on ARM. That is why you can install most iPad apps on macOS, and they typically work surprisingly well without any customization. Shared GPU and RAM are a game-changer for efficiency, speed, and battery life.
What is the distinction between computers and phones/tablets you're referring to?
PS FWIW I've used IIS all the way back in Windows XP days. It worked well enough for my needs at that point to run a basic web server from my home computer!
