(p. 89) Jobs had no use for small-minded naysayers. His experience had taught him that if you offered a better computer, well priced and accessible, there was no limit to what human ingenuity could achieve with it. No one, after all, had thought of electronic spread-sheets when he and Wozniak rolled out the Apple II, in 1977, but within two years, a spreadsheet program called VisiCalc–created in an attic by a first-year Harvard MBA student and a programmer friend–was one of the strongest drivers of Apple Il sales. The PIC was not a consumer product like the Apple II, but the principle was the same. “People are inherently creative,” Jobs remarked to an interviewer a few years later. “They will use tools in ways the tool makers never thought possible.”

(Note: my strong impression is that the pagination is the same for the 2008 hardback and the 2009 paperback editions, except for part of the epilogue, which is revised and expanded in the paperback. I believe the passage above has the same page number in both editions.)
