From Apple.com: "Thumbscoop The challenge of the thumbscoop was to create a crisply machined scoop that was still comfortable to use. The designers at Apple worked on hundreds of versions of the thumbscoop even examining them under an electron microscope to get it right." Okay, so I understand that Johnny Ive and his buddies are amazing designers, but an ELECTRON microscope for a thumbscoop? Anyone who knows what an electron microscope does should know that that's incredibly excessive. How could that possibly help examine the thumbscoop which is gigantic at that scale?
