Earlier this month, in an interview with Charlie Rose on 60 Minutes, Gates became emotional, which is not a common thing with him, when he spoke about his last conversation with Jobs before he passed away in October 2011.  "He and I, in a sense, grew up together," Gates said. "We were within a year of the same age, and we were kind of naively optimistic and built big companies. And every fantasy we had about creating products and learning new things — we achieved all of it. And most of it as rivals. But we always retained a certain respect and communication, including even when he was sick."

As partners and rivals, they built the personal computing industry with two totally different styles. Jobs was a working-class kid from California who believed in tight control over all products, and put a premium on design. Bill Gates was an upper class kid from Washington who believed in open products, and didn't worry too much about great design, reports Business Insider.

"Each one thought he was smarter than the other one, but Steve generally treated Bill as someone who was slightly inferior, especially in matters of taste and style," said early Macintosh employee Andy Hertzfield in Walter Isaacson's Steve Jobs bio. He added, "Bill looked down on Steve because he couldn’t actually program."
