But the point is, an iPhone isn't a priceless piece of art. It's just a phone. And if you're going to dole out the cash for a pricy pro iPhone, why would you cover that up with rubber or plastic?
I've owned nearly every iPhone since Apple started making them, and I've only ever dropped my phone a handful of times, and I've never cracked a screen. Tiny dent here or there, but that's what happens to things you own.
To me, putting a case on your phone is akin to buying a beautiful new sofa, and then covering it in plastic. Or buying a Rolex and putting it in an Otterbox. Cheese city.
