People seem to be assuming that Apple arrogantly dismissed Google maps from iOS - but this isn't the case (according to what I heard). Google basically terminated the licence, or at least stipulated licence conditions that were simply not acceptable to Apple. No way are Apple prepared to leave such a core piece of functionality in the hands of a major competitor, so they had to move quickly to build their own solution.
In the short term, yes it probably suck. In the longer term, we'll hopefully end up with something much better than the **** sandwich Google were expecting us to eat.
On the positive side, the driving directions are great !
Where do you have heard it? Insider information?
