Or... or hear me out, I know this is absolutely insane as a concept but it may sell because people want a PORTABLE DEVICE to be thin and light.
I know, I am absolutely insane to even suggest such a crazy concept just imagine people don't want half a pound of metal in their pockets. Given this and other threads it seems like an impossible thing to even think about. Like how could anyone want a phone to be light. Stupid to even think about, in fact they should double the weight of the current pro since nobody cares about thin and lightness!
