Cases (for iPhone or iPad) oftenly do more harm than good. They tend to scratch the shiny parts of your device (chamfered edge, glass back, Al body) due to minor bumps when you move your devices.
After months of using case I realize my old iPod looks REALLY bad. After that I swear I would never use another cases for them. Go NAKED just as it intended.
I dont understand what's the point of covering a well designed piece of hardware with ugly casing? You use something like Otterbox and MAYBE, just MAYBE it will survive a few drops. But you also don't enjoy its lightness in the process.
Might as well buy a cheap tablet and covering it up. Makes no difference.
I often just use skinguard in the back for protecting it against surfaces and that's it. It does not interfere with my experience enjoying the decice.
