Like all earlier iPad models, the iPad 4th Gen (Wi-Fi Only, A1458) -- which some may choose to call the "iPad 4" and Apple formally called the "iPad with Retina Display" in marketing materials -- is a tablet computer for the web, e-mail, photos, video, music, gaming and more. The iPad 4th Gen models share essentially the same housing as the iPad 3rd Gen models before them, except that the iPad 4th Gen is equipped with a Lightning port (rather than the older Dock Connector port), and internally has a faster processor, faster Wi-Fi, and a better camera. The models equipped with cellular networking also provide 4G LTE support, although this specific model only has Wi-Fi. All iPad 4th Gen models feature a 9.7-inch 2048x1536 (264 ppi) multitouch glossy LED-backlit "retina" display, a dual-core 1.4 GHz Apple A6X "system on a chip" with quad core graphics, 1 GB of RAM, 16 GB, 32 GB, 64 GB, or 128 GB of flash memory storage, dual cameras -- a rear-mounted 5 megapixel "iSight" camera capable of shooting stills and 1080p video and a front-mounted 1.2 megapixel "FaceTime HD" camera capable of shooting stills and 720p video, dual-band 802.11n Wi-Fi, Bluetooth 4.0 and more. The battery life of this iPad 4th Gen model is reportedly 10 hours "surfing the web on Wi-Fi, watching video, or listening to music." The 128 GB configurations, introduced January 29, 2013, are order numbers ME392LL/A and ME393LL/A, in black and white, respectively.
