Why? Are you not afraid of dropping your phone on the floor at home?
In all the years I've had iPhones (since Day One, Launch Day of the very first one in 2007) I have only dropped an iPhone twice -- once at home, and thankfully she landed on my oriental rug rather than on the bare hardwood floor or the kitchen floor -- and once in a store, where actually I didn't drop it, the iPhone slid out of the pouch I was using back then and went sailing....landed screen-down on the store's slippery floor, slid along a little before then coming to a stop. With my breath held, I ran to her, reached down to pick her up.....and not a scratch on her, no cracks anywhere, she worked just fine, as always. WHEW!!! The friend who was with me was watching anxiously and was relieved when I said, "I think my phone's OK!"
Not to say that I won't one day or evening drop either the iPhone 11 Pro or the iPhone XS (the one I use as my "home phone"/landline replacement so that I can keep the number that I have had for many years, long before cell phones), but so far I've managed not to do so. When I'm not actually using either iPhone, they sit in their own nice little stands -- during the day, near the computer workstation, and at night, on identical stands in the bedroom on top of the chest of drawers. When either needs to be charged I stick it on the charging dock, and again I have one of those in the living room area and one in the bedroom. In the nice weather when I'm out on the deck, I usually have the sliding door open so I can easily hear the phone if a call comes in. When it's time to take a trip to the library, the store or somewhere else, I slip the iPhone 11 Pro into her case and that protects her somewhat. I am not, and never have been, a believer in screen protectors. Ugh, remember those awful ones that were first offered, the ones that turned all orange-peel looking?!
I like to admire the beauty of my iPhones -- and I like the way they feel in my hand, although, yes, some models have been and/or are slippery to hold, a bit of a hazard! I think my favorite iPhone for looks was the gorgeous Piano Black iPhone 7 and 7 Plus. Just a delight to look at and to hold! Right now I'm rocking the lovely green iPhone 11 Pro and the lovely Space Black of the XS. I noticed when looking at photos of the new iPhones that instead of Space Black this year, Apple is offering "Graphite," which looks almost as though it would match my new Polished Metal Metallic car! LOL! (Uh-oh, dangerous thinking there -- mustn't go there, must step away from that thought, push it out of my mind right now!!!......).
Many cases are too bulky or add bulk to the iPhone and I don't like that. Years ago I tried a clear see-through hard plastic case on one and was really afraid I'd scratch the iPhone when I had to remove it for some reason, and it was the devil to get off, too. I took it off and left it off and that took care of that case.....The rest of that year the iPhone went naked both at home and away from home. In looking at the selection of cases from Apple this year, I don't see any of the regular Leather cases for the iPhone 12 Pro / 12 Max, and all they're offering is the ones which would work with the Magsafe doohickey. That's too bad, really. If I were buying a new iPhone 12 Pro I'd be having to look elsewhere at third-party options for a case to suit me....
