I do and I payed a good amount of money for it too. I am overly cautious when it comes to expensive things but it has saved the phone from some damage at least as I've dropped it a few times over the years.
Also I like the idea of a drop proof phone case. I get what you mean but all I can see is a phone with some kind of anti-gravity-science-thing attached to it.
I had a case on my third gen iPod Touch but only after the chrome back got scratched to hell. No case on my iPhone 4 I've had since Verizon started carrying them, and not a scratch on it. I must have above-average motor skills because I've never dropped a phone in my life.
I despise cases (I never used one with my old Galaxy Nexus or Galaxy S) but I would rather have a cheap case and protect my iPhone than have to pay to replace the screen, so I settled on a 2mm thick case off Ebay that I actually like quite a bit (It's actually saved my phone twice now). Plus it was like 2 bucks. I would never use on of those Otterbox cases though, those are ridiculous. When I see those people that have those Otterbox cases on Samsung GS3s or GS4s it breaks my brain. You practically need a backpack to carry those things.
Doubles my battery life, and they gave me two for the price of one.
Which was nice.
Yes because it seems incredibly dumb to not have one on such a fragile and expensive piece of technology.
Pretty much this. I'm dead certain that the screen on my phone would have cracked by now if I didn't use a case. I've had it for over a year now and it still doesn't have a single scratch.
Don't like the extra bulk in my pocket. Plus, I'm amazingly talented when it comes to not dropping things. On the rare occasion I do drop something, I almost always catch the object I drop with the same hand that dropped it before it hits the ground.
It's like that scene in Ronin where DeNiro is testing that German guy's reflexes.
Little story about why it is worth it. I got a brand new HTC Sensation and I loved that phone. Rooted, custom rom, awesome. I about a month later had fostered a dog because I wanted to see how the family would do with a dog in the house. Things are great, phone and dog. Now, one night, I was looking at phone cases. I thought maybe I should invest in one. I saw it, saw the price and figured.... Nah, I'll be fine.
Next day, I kid you not, going to walk the dog. Excited to go for her walk, she jumps into me and bumps my phone out of my hand. Lands right on the corner, SMASH. It hit the lower right corner and the glass on the screen was destroyed. The screen still worked luckily but maybe the case could have protected it. I don't know but in the end, I had to go back to the default RUU, take off root and pay $150 for a new phone. Isn't that awesome?
It might not look purty or sleek, but if it can save you money, just get the case.
