I agree it may be worse or it may be nothing, but then just scrap the forum altogether? I mean, since none of us have actually handled every unit of a device, should we abandon discussion because it might mean nothing?
I consider the forums to be an invaluable source of info because other people will have experiences with a device that I can't have until I buy one. Before giving my money, I'd like to see what others have to say. I don't know about you, but if someone says this is the first time their iPhone dropped from waist height while in a case and still chipped, that doesn't fill me with confidence. If you have a 17 Pro, hopefully yours is pristine after 10 drops, but this is the kind of stuff I want to know, even if it is an echo chamber. I wanna know if someone got scuffs and dents very quickly and I want to hear if someone's phone is fine. It helps me make a decision should I consider purchasing one.
And "it's an echo chamber" can be said about every thread of this forum because we as Apple enthusiasts are a very small minority.
