The iPhone wasn't as revolutionary as we like to think. It was absolutely a tipping point moment, but it was also an iteration from predecessors. I was an avid Palm Pilot user in the early days, and later a Palm Treo user. The Blackberry and HP's iPAQ are arguably predecessors that influenced the iPhones design. I still use Swype as the main mode of text entry for my Android phone, and Swype was originally inspired by Palm's Graffiti. Each of these predecessors had, in retrospect, some significant flaws, but that's what incrementalism is all about -- learning and adapting, which is what the iPhone represented.
