When microsoft released IE everyone considered it a joke. It had no marketshare, nobody wanted to use it, and the common opinion was that microsoft was doomed beause netscape was going to make windows superfluous. What could be learned from what happened after were two lessons: (1) public opinion is not the end-all decider of a product's chances, and (2) when microsoft hooks something on the windows train it has incredible momentum, even when it doesn't seem like it. WP8 is hooked on that train in a way that previous windows mobile variants weren't.
