InvisibleSHIELD for iPod nano

For the iPod nano purist at heart, Protective Solutions Inc. has whipped out an InvisibleSHIELD that covers the entire body with a pretty durable looking clear plastic film – preserving the iPod's beauty Ive labored so long to produce. They also have a video of various people doing stress tests with pens and car keys, just to really strut their stuff.

I'm still looking around for a case for my black nano, and I go back and forth on whether I want to preserve the nano's sleek exterior with something like this shield, or if I want to dress it up like the Michelin Man. At $20 it might be a little steep, but I'm wondering: have any of you TUAW readers used one of their shields before? Please share any experiences you've had with the rest of the class.
