The 12.9-inch iPad Pro was announced on September 9, 2015 at Apple's annual event in San Francisco. The biggest iOS device to date, it boasts a 12.9-inch retina display at 2732x2048. That's 5.6-million pixels—more than the 15-inch MacBook Pro. And it's just 6.9mm thin and weighs in at 1.57lbs. A new, 9.7-inch iPad Pro was introduced at a special event on March 21, 2016.
The 12.9-inch model is powered by Apple's 3rd-generation 64-bit processor—the A9X. It also offers 4 GB of RAM with 2x the memory bandwidth of the A8X. It comes in silver, space gray, and gold, with 32 GB and 128 GB of storage. The 128 GB version also has optional LTE networking.
To add to the immersive experience, Apple has also added a 4-speaker audio system for the first time in an iOS device, and it puts out 3x the volume of the iPad 2.
Orders for the original iPad Pro began on November 11, 2015, with in-store availability later the same week starting at $799.
The iPad Pro also features a Smart Connector that allows for accessory connections, like that of the Smart Keyboard. Also available is the Apple Pencil — an Apple stylus that makes the iPad Pro do all kinds of awesome. Apple Pencil uses force and multiple sensors to perform various actions that are incredibly low-latency and extremely accurate.
During their special event on March 21, 2016, Apple introduced a smaller 9.7-inch iPad Pro. The new model features what Apple calls a True Tone display, which measures the temperature color of ambient light and changes the warmth of the display to match.
