As taught by Steve Jobs from inside Apple design, that every designer must know.
There is "10" in the title and just 8 listed haha
Shoutout for Jony Ive who inspire Steve
"form follows function" permeates through other areas. Once watched a video on 4x4 off-roading where someone mentioned people adding fancy gimmicks to their vehicles without purpose ends up being detrimental to the sport. A lot of items hung on the exterior end up as tree decorations in the forest.
Interesting to see it applied in other areas, never thought of Apple that way before.
