Sold in two versions, XtremeMac's MicroShield ($20) for iPod nano is almost identical to Tunewear's earlier Tuneshell, offering a two-piece clear hard plastic case with a snap-in front cover. XtremeMac includes a carabiner hook and Click Wheel cover with the base version of MicroShield, and offers a $30 version that replaces the hook with a second clear rear shell that has an integrated belt clip.
