Ten years ago, the original iPhone ushered in a new world for mobile computing and sparked the bring-your-own-device (BYOD) movement at work. Soon after it arrived, iPhones were showing up everywhere in the office, forcing companies to quickly scramble to figure out how to manage them.

The iPhone X, with its distinctive "notch" at the top and the inky blacks of an OLED display.
That sleek (and deceptively simple) device not only debuted a new touchscreen that would radically change how people interact with technology, it also shook up carrier control, set a new target for Apple’s competitors to aim for and created a platform for countless mobile app developers. Oh, and it eventually gave birth to a highly successful tablet boom with the iPad.
