Sure their will be.. Apples numbers state the trend is continuing and we are NOT fully saturated, by a Long shot. Personally, I agree with those sentiments comparing to real life experience. The generation below us has 7 year olds with iPhones. As time goes on this will become standard for those worried parents who can track their children's location from these phones. The first thing I am going to do when I have children is do this as well... Until they are teens of course, then they can go off on their own.
You show a lack of knowledge in every aspect of this changin environment daily. Stop embarrassing yourself. Even my grandparents just picked up iPhones for some of the amazing apps which help them everyday. Get a clue or get lost! Stop spewing misleading and flat out wrong information.
The numbers don't lie. S KILLED estimates and will rise. Slowly but surely.
