I don't know that I buy that. Development efforts have trouble all the time, no doubt even inside Apple. The problem here isn't that maps was late, it's that someone decided to pull the trigger and ship it when it wasn't ready. That's not something that can be put on the development group.

Pulling out the dead guy card again: one generally would assume that Jobs would have been using this thing and playing with it to be sure it was ready. Did Cook? Or if not, whose job was it and why didn't it happen?
