I recently purchased an iPad Air and I want to buy a case for it, but I'm unsure of exactly what type of case. I had the original iPad before, with a thick Otterbox case, but that case completely destroyed the sleekness of the iPad and after a while it got quite dirty around the sides of the screen. I want to get a lighter case, something like Apple's Smart Case, but at the same time I don't want to end up with a cracked screen from dropping it. Would the Smart Case provide sufficient protection? I will be using the iPad every day, and it'll be moved around a lot.
