Or maybe they didn't re-use much of the design, other than a nostalgic reference to a time before "chamfered" bezels. iPhone 4: 4.5 H x 2.31 W x 0.37 D inches; iPhone 12 mini: 5.18 H x 2.53 W x 0.29 D inches. 22% thinner, much different feel in the hand. And obviously, if you have a regular or Pro Max iPhone 12, a completely different aspect ratio.Good point but at least in that exception they didn’t come up with that slide of “design evolution” from the first to the last generation to acknowledge that change. That would have been a fun one.
It's almost bizarre how small the older iPhones feel, since we've all gotten used to larger (particularly taller) devices.
