I'm rocking my X naked, just like I've done with every iPhone since the 4. I remember occasionally using a case on my 3G and 3GS, but by the time I got to the 4S I decided to just skip it entirely and enjoy the phones' design ... my X does have two hairline scratches on the screen; I got them when the phone was about three hours old - my wife accidentally dragged it across the floor, face-down, while trying to straighten up the bed (the extra long cable was tangled on something, and she pulled it, not realizing the phone was attached. Lol) ... But whatever. It's just a phone, and a gorgeous one at that!
