Two things I find fascinating about this display of 2nd hand phones in CEX.

1) Every phone faces *backwards*! Devices are all monolithic black rectangles from the front. So the camera cluster is the only thing which can be used to identify them.

2) All the price tags in store are 3 colour eInk displays! They're now cheap enough in bulk to be used everywhere. They also had some eReader sized displays as well, but they were monochrome.
