iPhone

The original iPhone hit in 2007 like a hurricane, instantly changing what mobile phones were expected to do, from the edge-to-edge glass screen, to the colorful icons, to the most responsive (and perhaps only) touch screen that many had ever used.

Today, the idea of icons, apps, touch screens, and even traditional Web browsers on a phone are commonplace, but even the phones that have leapfrogged the iPhone in terms of components and features must surely admit their debt to the original.
