iOS was one of the earliest mobile operating systems but lacked many features when first introduced such as multitasking, third-party apps, copy and paste functionality, attaching files to emails, and MMS support. However, iOS introduced innovative gestures like pinch-to-zoom and inertial scrolling, provided an amazing speed and direct user experience, included the first true mobile browser in Mobile Safari, and its "Springboard" home screen redefined the mobile computing experience.
