"Ah, the look and feel of a metal phone body..as you slip it in that new case to protect it," remarked another reader, AStepInTime, "Sort of like putting seat covers on your new car -- or sofa.."I don't know if the car seat-cover analogy is quite correct since you're actually covering your entire phone, But close enough, The fact is today's high-end smartphones are incredibly well-designed, sleek electronic devices -- except for the fact that they require a companion accessory to safely survive day-to-day living with their obliq xtreme pro iphone 6s / iphone 6 dual layered tough case - blue reviews human owners, It's a weird conceit, and one that we've all grown to accept..

I think the whole existence of the case industry highlights the fact that modern smartphones have two basic problems. And as phones get larger and more sophisticated, those flaws seem to be getting worse, not better. Look around next time you're in an airport, on a train, or at a Starbucks. I bet almost everyone in your field of vision has a case on his or her phone. Of course, there's a class of confident souls who carry their phones naked, sans case. Many never have a problem. Others aren't so lucky, as evidenced by the number of people I see riding the New York City subway using case-less phones with cracked screens.

Some, including Recode's Walt Mossberg, chalk the flaw up to human error, It was Walt's fault he dropped the phone, but why shouldn't it survive a 5-foot fall onto concrete, let alone a 4-foot fall onto a gymnasium floor that a butterfingered friend of mine experienced recently (the screen shattered), Cars have bumpers on them, Smartphones don't, Which is why we put our obliq xtreme pro iphone 6s / iphone 6 dual layered tough case - blue reviews own bumpers on them, And screen covers, Both cottage industries are flourishing, Compare that to 10 or 15 years ago -- I bet your old flip phone or old-school BlackBerry could take a beating and come back for more..

Insurance is an option. But who wants to pay even more money for a phone that already costs too much to begin with. And AT&T, for example, has a $200 deductible for any higher-end phone you insure. So a case seems like the most cost-effective protection solution, and if it helps keep your device in pristine condition, you might get more money for it on eBay or a trade-in down the road when you buy your next $750 phone. Speaking of pristine, the other problem with today's smartphones is that the sleeker they are, the worse they look with any sort of blemish. Drop your iPhone 6 or 6 Plus the right way and you may just end up with a dented corner because metal dents, it doesn't break. But there's no body shop to take your iPhone to. The dent stays. Some can live with it. Others decide to hide it with a case.
