Perhaps there aren't more biographies of Steve Jobs, because the general public does not really consider Jobs to be "an important historical figure of our time" (and neither Apple to be the most important technological company of our time)?
IMHO, when the iPhone came out, it did not introduce almost anything revolutionary over the already available Windows Mobile PDA devices, it only simplified, polished and packaged the device way better. I still do not understand how Microsoft, considering their extensive experience in operating system development, somehow managed to lose their entire, massive mobile device market share in the course of only a couple of years. All it could have taken for Microsoft to win over Apple was to switch Windows Mobile from a cumbersome stylus-based UI to a convenient touch-based UI without wasting years and years to re-develop the misguided Windows Phone from scratch.
