It's difficult to overstate how dramatically Steve Jobs reshaped how we interact with computers. The irascible, brilliant impresario led a transition from minicomputers and IBM PCs squashed into beige metal boxes to the Macintosh, the iPhone, and the concept that technology should be fun to use.
Thanks to more than a dozen books about the Apple co-founder, and movies like Pirates of Silicon Valley, much of Jobs' life has become well-known. He started Apple with legendary engineer Steve Wozniak, at a time when the personal computer industry barely existed, after dropping out of Reed College.
