Yes it does look low res especially compared to the 6 Plus. You can keep saying the "Apple marketing line" but the difference from 720p to 1080p is very noticeable even on a 5" screen.Seriously? The iP6 screen looks pixelated and "low res" to you? You must have some super-human vision. All 1080p is going to do on a less than 5" display is use up more power.
