Mr. Jobs's pursuit for aesthetic beauty sometimes bordered on the extreme. George Crow, an Apple engineer in the 1980s and again from 1998 to 2005, recalls how Mr. Jobs wanted to make even the inside of computers beautiful. On the original Macintosh PC, Mr. Crow says Mr. Jobs wanted the internal wiring to be in the colors of Apple's early rainbow logo. Mr. Crow says he eventually convinced Mr. Jobs it was an unnecessary expense.
