iPad Mini 3 WiFi 2014 (A1599)
The iPad mini 3 models -- including this Wi-Fi only model (A1599) -- are quite similar to the previously introduced iPad mini 2 models, but are available in a white and gold colored housing (in addition to white and silver and black and space gray) and include a "Touch ID" fingerprint sensor. They have a variety of different identifiers, too.
The iPad mini 3 models 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, 64 GB, or 128 GB of flash memory storage.
