The iPad mini 2 models use practically identical housings as the original iPad mini, but have a much higher resolution "Retina" display and a faster processor. All of the iPad mini (2nd Gen) devices are packed in thin white and silver or black and medium colored gunmetal "Space Gray" cases and feature a 7.9" 2048x1536 (326 ppi) LED-backlit IPS touch-sensitive display, a dual core 1.3 GHz Apple A7 processor, 1 GB of RAM, and 16 GB, 32 GB, 64 GB, or 128 GB of flash memory storage.
Other notable features include 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 and Bluetooth 4.0, as well as dual microphones and speakers. Connectivity to computers, if desired, and power is provided by the Lightning port.
