Im really intrigued by these suggestions which happen a lot.
What, do you think, should be done with the iPad or the iPhone?
They reached peak design, they are heading slowly to lighter, thinner, faster.... better cameras, faster processors, longer batteries, thinner designs.... but it's still recognisably an iPad and will continue to be so for a fair while longer.
But what next? What do we realistically expect to change year on year? The times of rapid change and development for these devices is over.
All you can expect is tweaks here and there. Do you want a triangular shaped iPad?
Sure, at some point in the future tech will leap forward again and we will get folding/rolling/virtual displays perhaps.
.... but to suggest people at Apple arent visionaries because in 2024 you dont have your sci fi iPad and iPhone is just a touch unrealistic.
