Today is the first day that I will be using the iPad Air full time in place of the 10.5-inch iPad Pro that it is replacing. Not sure whether I am liking the placement of the Touch ID sensor at the top on the power button. Having been using the iPad Pro 10.5 for three years and using the iPad Mini 5 muscle memory is trained to press my thumb at the bottom of the screen to turn on and unlock the device. I’ve caught myself picking up the Air and putting my thumb were the home button used to be only to realize that does nothing but turn the screen on. No doubt I will re-learn a new behavior, but I can see how Face ID would be a better experience.
