Original iPhone

The smartphone that transformed the industry, the original iPhone 2G has an impressive legacy. Developed in secret, it revolutionized cellphone design, becoming one of the first slate form factor phones, removing nearly all physical controls in favor of a touchscreen interface. Released in 2007, it featured one of the first touch screens that was not resistive, requiring no pressure or stylus. The iPhone 2G also featured the first full-featured web browser, and essentially launched the market for apps with the introduction of the App Store, making third-party apps easy to access and download.
