Bell curve: I’m designing for a company that makes retail home decor stuff. The interesting thing about Yo’s curve is how subtle changes bump the product from $ category to $$$ category. Just a little more attention to molding (ie less flash, less witness lines, more attention to sink marks). Materials (obviously). Little bespoke additions, like a dot matrix LCD in place of a standard 7 segment cheapo. It’s really brought that to my attention.
Ranges: Why are you so against plastics? I’m against bad design and bad engineering, not against any material per se.
