The death of Windows Phone.
Windows Phone differed from other designs for a few reasons—and not just regarding app support. A key challenge in modern design is creating a system that appeals to the user—specifically, one that draws you in so deeply that you lose control over your own actions. That is why iOS and Android are addictive; they compel you to do things you hadn't originally intended to do. I often catch myself doom-scrolling or doing things I never meant to do. With Windows Phone, you had to customize the tiles yourself. That was difficult, and the system could be complex for a newcomer—it certainly was for me. But eventually, you got used to it. Windows Phone didn't create that kind of addiction. That was part of the problem: they built the system around the "Metro" design language—literally deriving everything from it. Consequently, elements like the fonts couldn't generate the same effect as the animations found in iOS or the general user experience of Android. The project was doomed regardless. Microsoft is incapable of doing anything right; they simply kill off devices for no reason—creating them only to destroy them. Windows Phone didn't mindlessly copy iOS, nor did it force the user to perform specific system actions. However, it did force the user to make choices that the average consumer simply wasn't equipped to make.
