TPU cases are becoming more common these days, and that's not a bad thing because the material is a good compromise between shock protection and a grippable material. The Belkin Grip Vue has been a popular case, and today we take a look at the new updated iPod version. The Grip Vue is a simple design, being a single piece of TPU made to hug around the iPod's body. Of course, there's all the port cutouts and covers over the volume rockers. In case you don't know what TPU is, it's material that's best described as harder than silicon but softer and more flexible that plastic.
