How far has the iPhone’s display come? This screenshot says it all
The iPhone has come a long way since its original 3.5-inch, 480 x 320 display. Now the iPhone 6 Plus ships with a massive 5.5-inch, 1920 x 1080 “Retina HD” display with individual pixels that are basically indiscernible to the human eye.
The above screenshot shows an original iPhone screenshot inside a 6 Plus screenshot. It doesn’t even fill a fourth of the new resolution.
