Right on cue, accessory manufacturer Case-mate has come up with a new range to cater for the newly announced iPod touch and iPod nano that are in their second and fourth generations, respectively. The Clear Armor is the latest Case-mate offering that will offer unprecedented protection to your shiny new purchases against unwanted knocks and scratches as you bandy them around on your travels. Just to get an idea of how strong the Clear Armor is, it was originally concocted to protect Apache Helicopter blades from sand damage. Fancy making an upgrade, or do you have any other better recommendations for the new iPod nano 4G and iPod touch 2G?
