I never owned a 3rd gen iPad but I can only image how those who did felt when Apple released the 4th gen only 8 months later. That’s what the 2020 Magic Keyboard reminds me of. The 3rd gen iPad probably should never have been released as Apple didn’t have silicon ready to support the Retina display. They had to know the A5X wasn’t good enough. I would say similarity with the Magic Keyboard they had to know what was in the pipeline for iPad and they should have been able to design for it. The new Magic Keyboard is backwards compatible (Apple is no longer selling the old one) and there’s no indication it includes any new or different functionality. So why wasn’t it designed this way to begin with?
