And again, that's 20/20 hindsight. Go look at the tablets that were on sale in 2009. Do you think that the innovation fairy just started shooting Skittles out that magically gave the iPad a huge leap? Innovation isn't always in engineering terms, boosting cycles etc. Sometimes it's in reimagining how things can be done. Even a technology considered relatively mature (cars) changes a lot, in subtle yet important details. Just because you can't foresee change in existing markets doesn't mean it won't occur.
