Ok, so my iPod (4G 20gb) arrives tomorrow and, having seen the condition of the ipods that belong to my friends, I know I am going to need a case. My friends, all of which don't use cases, have an insane amount of scratches all over the back, front and screen of their ipod. I don't want this to happen to me. So, I read a handful of reviews of a few different cases. The one that really appeals to me is the iSkin evo2. But, I have heard some bad things about it (dust collection, melting parts to ipod...). The other one I kinda liked was the Speck Products Skin Tight Skin. I want something small like those, none of those crazy metal cases or ipod armor type things. Anyways, I wanted to ask fellow ipod users what they use to protect ther ipods and for any suggestions...?
