The iPad Air has never been the thinner and lighter version of the iPad. iPad Air 1 and 2 were the only full sized iPad in existence when they were released and the Air 3 was using the same chassis as the 10.5 inch iPad Pro.This should be called the iPad SE. The new air should be called iPad and then you have the iPad Pro line. iPad Air used to be the the thinner and lighter version of the iPad but now it’s nearly identical to the Pro line.
