er .... that is hard to say .,but what you describe really hook me
Besides larger screen this would be my wish for the next iPhone model... To move the Apple logo a few inches down, and change it from the chrome Apple into a transparent Apple logo with an white mini LED Diode That flash when an in coming call rings, also illuminates as the front screen illuminates. It will go dark just like the front screen to save battery. I think it is only fair since the Mac Book, and Mac Book Air have apps and facetime like iOS's That iOS should have a little something from Mac's family.
Like it or not I think that the sales would go through the roof because of the wow factor to be seen. That's my wish.
