The iPhone That Never Was

In 1990, three former Apple employees launched a company that epitomized the Silicon Valley dream. What they invented looked like an iPhone--more than a decade earlier. The device never came to be. Imagine a tech company so visionary that it can take an public. A "concept IPO," they called it. Picture the three founders, all former Apple employees, two of whom--software engineers Andy Hertzfeld and Bill Atkinson--were already Silicon Valley legends for their work creating the Apple Macintosh. Atkinson's prolific inventions included the double click and the drop down menu.
