The question is, what device are you upgrading from? There won’t be much reason to upgrade from a 2021 M1 iPad Pro (which is what I have), but that’s probably not the target audience.
I agree that they should add mini LED. Lack of mini LED is one of my only disappointments with the 2021 iPad Pro.
Well, I am currently using iPad Air 4 and I see no compelling reason to upgrade. The only thing I am not happy about is my Air’s screen with its washed out blacks. As soon as they put OLED, I will jump straight in.
