Developing an operating system (OS) is notoriously difficult — not just because the technology is complex, but also because convincing app developers and users to adopt your system is enormously challenging. Microsoft's foray into cellphone operating systems in the early 2010s exemplifies this struggle, despite the huge advantages it enjoyed with Windows in the PC realm. Despite billions in investment and big talk of a new OS to rival the duopoly of Android and iOS, history ultimately hung up on Windows Phone.
開發操作系統(OS)是出了名的困難,不僅因爲技術複雜,還因說服程式開發者,以及要用戶採用新系統極具挑戰性。微軟在2010年代初進軍手機操作系統折戟便是明證,即便它當時已在個人電腦(PC)端坐擁Windows的巨大優勢,並投入了數十億美元,大肆宣揚要開發一個新的OS來挑戰安卓和iOS的雙頭壟斷,但歷史最終還是否決了Windows Phone。
