Cases are lame. I hate them and have never owned one.
...but the iPhone 6 is the first phone where I needed to buy one because it's too slippery.
Thank god someone makes a case that's barely a case.
Didn't you start with the original iPhone? The metal-backed original iPhone is as slippery as the 6/6+ so why the sudden change?
I started with the 3G. It was sleek too, but nothing like this.
more resale-value (because less scratches etc) if you want to sell your phone and buy a new one.
