I was considering getting a case to, but after actually getting a feel for the phone, it's such a nice material that I don't want to be holding a plasticy cover over it. The screen is also anti-fingerprint marks any way.
I am now thinking of getting a phone sock or pouch to protect it from scratches when I'm carrying it around, like in my pocket, because the phone itself feels perfect as it is, 'naked' lol.
