I'm very happy with this skin.  It is a smooth black rubber, with an embossed "Blackberry" logo on the back.  It is very sleek and adds very little bulk, yet seems to provide a nice level of protection (I dropped my Curve with this on and it's still working just fine).  One question I had as I was shopping was whether or not this includes a face protector for the Curve.  It does not -- the face is not protected, so you may want to order separate face protectors to avoid scratching.  The skin provides good access to all buttons, including the popular "standby" button on top, and the two slots on top that I haven't figured out why they exist yet (cooling?).
