What is it with people wanting or even accepting of designs with waterfall screen edges? They have absolutely zero functional use. The idea that you can have notifications show on the thin slice of the edge - how is that even useful? It only would be usable at times when you set your device down screen first, which of course is not actually the smart thing to do in the first place. Who was it that made the one device where the screen wrapped all the way around? That too was really cool, because you had this glowing slab, but in reality, only other people would ever see the glowing back side of the device, so the only reason to have the back of the device active as a screen when the front is as well, is to show off? But even in this case, why does it matter to have the edges of the device active screen?
These waterfall screened devices are effectively jewelry - offering features that do nothing functional and are just there for visual impact.
