You don't associate mechanical keyboards with sleek portability... and you don't associate portable compact keyboards with great tactile feedback or mechanical travel.

Hey, they started with millimeters so any additional info is kinda passable (in my books) as a visual / imagination stimulus.
Sometimes it can be really helpful, like with the distance from Earth to Moon, almost 385 000 km — that’s yeah, a lot, this gives the facts.
…but, when I found out that all the planets from our solar system packed next to each other would fit into this gap with some space to spare — this gives the perspective.
