Hate it or love it, the original iPhone changed mobile phones (and mobile computing) forever. Up until 2007, smartphones just couldn't get it right—they were too complicated, often stylus-dependent, and offered an experience far inferior to the PCs they impishly imitated. The iPhone upended the industry by starting from scratch. In an aggressive win for minimalist design, it eschewed prevailing aesthetics and offered only an extraordinarily large touchscreen as its interface. Since its release, many things about the phone are now taken for granted as standards, including multitouch gestures, threaded text-messaging, and built-in data plans. By forcing every other phone to get smarter, the original iPhone became that rare device that divides the history of its entire category in two: before the iPhone and after the iPhone.
