The 32GB iPad mini 4 from Apple has a smaller form factor than its big brother, the iPad Air 2. The iPad mini 4 is just 6.1mm thin and weighs 0.67 lb. Its smaller form factor makes it easier to hold in one hand. The tablet's 7.9" Retina Display features a native resolution of 2048 x 1536, showing up to 3.1 million pixels at 326 PPI. The Retina Display's capacitive touchscreen lets you utilize all the multi-touch gestures of iOS 9. The iPad mini 4 features Apple SIM, which gives you the flexibility to choose from a variety of mobile data plans from select carriers right on your iPad as well as stay connected while traveling around the world. You'll also be able to download at up to 150 Mbps when away from a Wi-Fi network and create your own mobile hotspot, allowing you to share your mobile connection with other Wi-Fi enabled devices. The mini 4 features Apple's A8 processor with their 2nd Generation 64-bit architecture, allowing for more robust and powerful apps such as video editing, 3D modeling and CAD, and 3D gaming. Also, the A8 chip supports Metal, a more efficient technology that enables the iPad mini to render detailed graphics and visual effects. Accompanied by the A8 chip is the M8 motion coprocessor, which measures the motion of the iPad mini via the accelerometer, gyroscope, compass, and barometer, lightening the load of the A8 chip. This frees up the A8 chip to process multiple tasks while enabling it to maintain fast performance. The iPad mini may have the Retina Display, but it still manages to maintain its 9-hour battery life. That's because the A8 chip isn't just more powerful; it's also more efficient.
