Hey guys... so I have an 80gb iPod classic with an invisible shield on it, and I love the protection. Especially with the silver back... no smudges or anything, and obviously, my screen is totally protected. But I'm looking to get, with the back-to-school promotion, a mbp13 2.26 and a Nano 16gb. I've pretty much decided to get a shield for the computer, but I'm wondering about the Nano. So you guys think that just the screen protector would suffice? I don't think there's any silver/metal backing on the Nano, right? So there's nothing to get smudged or scratched up. Isn't the Nano pretty much all plastic? Just not sure whether or not I should get the full-body shield or just the screen shield. Any suggestions would be most helpful. Thanks guys.
