XtremeMac today announced a new version of its TuffWrap silicone case designed to fit the second-generation iPod nano. The $30 case features ridged sides for grip, as well as a built-in Click Wheel protector, removable screen protector, and a detachable belt clip. In addition, the TuffWrap comes with a special universal dock insert that accommodates the nano with the case on. “This practical add-on allows the nano to be inserted into a variety of speaker systems and other accessories without removing the case,” explains XtremeMac.
