Much of Apple's success with its devices had to do with their simplicity. They were — and still are — simpler and cleaner to use than competing devices, which tend to appeal to a wide range of people.
Recently, when Apple switched to all-USB-C ports on its MacBook Pros, the simplicity is fading. USB-C is indeed designed to make things easier and better. It allows you to plug everything you'd usually plug into your computer into one single port instead of having a bunch of connected accessories sticking out from all sides of your laptop. But the company was arguably too aggressive with switching to USB-C, as many people aren't ready to make the switch, especially when it entails buying dongles, adapters, and expensive docking stations to benefit from it.
