I disagree.
Apple could do it if they wanted to, they just won't because the bump is what they are using as a branding thing.
And no, I have not forgotten that cameras have gotten better. However, I don't need that camera. I am not a pro photographer, a vlogger or someone that needs to take pics in the dark.
As I have mentioned MANY times here, 99% of my camera roll is photos taken of the stuff sitting on Walmart's shelves so my wife can decide which brand of ice cream or cookies she wants me to bring home. Why do I need the current Apple camera for that? So my wife can decide which tub of ice cream or box of cookies?!
Most of the rest are screen caps to show others something. The camera is just not a feature I use.
That said other people do use it, which goes back to my previous argument that Apple could if they wanted.
