Since my original iPhone, I’ve been against cases and protectors. Yes, screens can crack and make lovely spiderweb patterns you have to read through, but generally speaking, iPhones (and many other gadgets) can deal with everyday wear-and-tear.
I’ll go so far as to say I like the look of a worn, scratched up iPhone.
I comped mine up next to Han Solo’s blaster. You be the judge.
And yes, my phone still works perfectly, with no cracks on the screen.
