One of Levy's favorites is Don Norman's The design of everyday things:
... one of his big themes - creators should understand that their users are not necessarily the same as themselves. Writing at a time when such concepts were barely known to the general public, Norman, a world-class crank, instructively eviserates the product design of doors, telephones, air-traffic systems, and computers ...But do you think Levy's wife actually threw out his MacBook Air with a pile of papers, and that Steve Jobs yelled at his son? :)
