Or a set of lenses on the back that have to be protected from scratching. Yes, like every other phone, but what an aesthetic disaster.
I thought using the iPhone without a case would be a status symbol—"I've got so much money, I don't have to worry about destroying this $1,000 pocket computer." Who are the only people I ever see without an iPhone case? The characters on AppleTV+ shows! Everyone else HAS to use a case, not to avoid scratches but because an iPhone is slicker than a wet bar of Irish Spring.
