A dark blue iPhone would be very nice. If this color appeals to me enough, I might consider upgrading and continue staying caseless.
I've stopped using cases ever since my iPhone XS flew from my hands and landed face-down at a small road in my old uni. My heart stopped beating for a few nanoseconds. I was incredibly lucky, though—my phone survived.
I was using using a very thin case at the time. The most noticeable damage was minor scuffs in one of the corners and a very, very tiny nick at the top of my screen [you'd think it was just dust]. It was a miracle, really. I never bothered putting it in a case since then.
