Completely Naked?

Is anyone using this phone completely naked? No case, no screen protector, no back protection? I asked this another way a little earlier; only one response. Very curious. I'm looking at the Z5 Compact and the Samsung S6 Edge. I prefer the specs and size of the Z5, but I know 2 people who use their Edge without any protection. After several months, they still look good.

All opinions appreciated.

Thanks.
