I personally liked the physical appearance of the iPhone 5/S better. This one looks like an updated 2nd generation iPod touch tbh. But the screen size is impressive
Samsung claimed during the patent-infringement trials against Apple that one of the main reasons people buy Samsung devices is for their bigger screens. If that's no longer a differentiator, Samsung's sales could suffer. Now that Apple has bigger devices, Android makers such as Samsung and LG won't have as much of an advantage.
