Why is this interesting? I suppose because it's Apple, and they patented it?
I'm sure they're expensive to produce/store/transport, which is why we've been using flatpack pizza boxes forever.
Yeah, they have the patent for the pizza box. Why expensive to transport instead it would have reduced the material. It's quite a small box as compared to the square box.
Theoretically expensive because when you ship a pallet of pizza boxes to a pizza joint, they come in a very compact completely flat stack.
