The fourth generation iPad (sold as iPad with Retina display, sometimes called the iPad 4) is a tablet computer that is made and sold by Apple Inc. The fourth generation iPad kept the same Retina display as the last generation, but added some new features such as the Apple A6X chip, and the Lightning connector, which replaced the 30-pin dock connector. It was shipped with iOS 6, but can run the latest version of iOS, which is iOS 8.
