The 12.9-Inch iPad Pro devices pack an "epic" fully-laminated 12.9-inch oxide TFT touch-sensitive Retina display with 5.6 million pixels (2732x2048 at 264 ppi) with a variable refresh rate and a fingerprint-resistant, antireflective coating. It is powered by an Apple A9X processor, has 4 GB of RAM, and this model has 128 GB or 256 GB of flash memory storage.
Other notable features include dual cameras -- a rear-mounted 8 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 4.2, as well as dual microphones and two sets of stereo speakers designed to automatically switch to the set that is least likely to be muffled by the user.
Connectivity to computers, if desired, and power is provided by a Lightning port. A new "Smart Connector" provides connectivity for a new optional Apple Smart Keyboard (A1636, MJYR2LL/A, US$169) -- reminiscent of the Microsoft Surface Keyboard Cover -- as well as third-party keyboards. Additional input is available courtesy of a new optional "Apple Pencil" (A1603, US$99), which provides a variety of pressure sensitive sketching and drawing options.
