Kudos to apple for indtroducing high res displays into devices with the iphone 4, but since then the 4s, 5, 5s, 6, 6s have all stayed at the same res of 326ppi. Compared to the 6plus 400ppi there is a huge difference in clarity. To me, if the res is still 326ppi that would be a deal breaker as it's no longer good enough in 2016.
