Griffin Technology today announced a new line of innovative cases for iPod. The company is shipping four new models to retailers today, followed by a steady stream of new case products throughout the year with plans for a 2006 holiday collection. Griffin’s emphasis will be on unique features and compelling designs, the company says. Griffin enters the iPod case market just in time for back-to-school with new cases for the 30GB and 60GB video iPod and the nano. This new line is expected to hit retail shelves over the course of the next month and retail between US$19.99 and $29.99. New offerings include the trio, vizor, tempo, and iClear.
