Wraps are nice because they're not permanent and don't affect resale value. Having a car without a wrap might soon be as unusual as a phone without a case.
I know more than a few people with very expensive phones covered in thin carbon fiber style cases which are there purely to protect the glass and metal from egregious scratches, though.
I would never sit hours somewhere waiting to get my phone fixed, I value my time.
The ecosystem?
Its a phone, not a tank.
People not using cases on their phone are insane to me. I can't even sit these spaceships down on a non-flat surface without them sliding off. They're the thickness of playing cards.
Similar to: "I bought my phone for identity, for style, for a feeling if being on the technology edge."
Yeah, I bought a phone with a web browser in an ecosystem I like.
