“My favorite scenes were meeting suppliers,” said a former Apple executive who had traveled with Mr. Cook frequently and asked to remain anonymous because he did not want to upset their relationship. “He is Mr. Spreadsheet. If things weren’t right, he would torture the suppliers and demand improvement. At the same time, he had good relationships with them.”

This entire article is nice and all, but left me with this one thought: Does “Mr. Spreadsheet” use Excel or Apple’s own Numbers program? It’s got to be Numbers right? But then, really, Numbers?
