i think you definately have a point there. I'm in two minds about it, after all I would have ordered an iPhone 12 without the magnets and a slightly bigger battery.
But I guess this is apple being apple, they have to do something different from the competition and it does somewhat solve the alignment issue which allows for effecient faster wireless charging. I'm just not sure how important faster wireless charging is, i tend to charge my phone slowly overnight which is better for the life of the phone. Early reviews don't show the cases slotting on and off the phone easily like the marketing video suggests either...
