As a design student back in the 1980s, a teenage Jony Ive spent a semester with a design agency in London, the Roberts Weaver Group. One of his first projects was designing a new pen for Japan’s Zebra Co. Ltd., a pen-maker based in Tokyo.
Ive’s TX2 pen was made of white plastic — the beginning of a life-long obsession with the color — and had a pair of rubbery side panels for a better grip. But what set the pen apart from every other was a nonessential feature — a ball-and-clip mechanism on the top that served no purpose other than to give the owner something to fiddle with.
Ive noticed that people fiddled with their pens all the time. So he decided to give his pen something he called the “fiddle factor.” This crucial insight ultimately became an essential element of Apple design as Ive rose to become Cupertino’s chief design officer.
