Apple has added the iPad Air and Mini to round out the iPad Pro and iPad range.
The iPad Air and Mini gain Apple’s A12 Bionic chip with neural engine (the iPad has an A10), Apple 1st-gen
pencil support and have 10.5-inch and 7.9-inch Retina displays.
They are not replacements for the 12.9 or 11-inch iPad Pro which has a more powerful A12X Bionic chip, higher Liquid Retina screen, 2nd-gen Apple Pencil support and the all-important USB-C port.
Apple also offers a trade-in program – see here.
