I have always used a case with past and present smartphones. I held onto my Dinc until this phone was out~considered the iPhone 4 and 4S, but hated the glass back design~if I want a work of art, I'll go see it in a museum, not carry the fragile double glass sided thing around with me 24/7. Compared to the iPhone, the Rezound seems built well, but I still have it cased. Call me paranoid and practical. I tend to favor high-quality TPU cases, and currently have the Verizon silicone cases (in 3 colors) for my baby. As I haven't found a holster I like yet, I have it in a leather pouch with a rotating clip that I got from Amazon that fits it like a glove. Otterbox seems like over-kill, and I know I wouldn't like the screen protector. I am waiting for Seidio to make the Surface case/holster for the Rezound, which should be available soon.
