XtremeMac has introduced MicroShield and MicroShield Plus cases for the iPod classic, iPod touch, and iPod nano (with video). MicroShield Plus cases are made from clear impact-resistant plastic, and include a removable belt clip that doubles as a kickstand. The MicroShield Plus for iPod nano comes with two backs—one with a belt clip and one without—and a carabiner that can be easily attached to a belt, purse or backpack. MicroShield cases without belt clips are also available for all three new iPod models; all MicroShield and MicroShield Plus cases include TuffShield protectors for the screen (iPod touch) or Click Wheel (iPod classic, nano). XtremeMac MicroShield and MicroShield Plus cases sell for $20 and $30, respectively, and can be pre-ordered now, with availability expected in the coming weeks.
