Also, note even the paper of the user guide and the rivets used to bind the paper. They show great care. Most people (myself included) would have just printed on normal paper and stapled them together.

Nothing special. Elementary school kids use them every day.
Yes, using brass fasteners instead of binding the papers into a true book shows a level of care similar to what I did when I was 4 years old in 1976 in my preschool class binding pictures of trees and dinosaurs together.
You seem like a fan of Apple, so I'm sure you can appreciate the exquisite font used on the Clear / Reset / Push button mechanism.
