If you want to protect your new sports car against scratches, you just put a thin layer of coating over it, you don't go down to your nearest military surplus store and ask for some spare tank armour do you? Why? Because if you pay a premium for a sports car you want it to look like a premium sports car - not something built for Robot Wars!
So in light of this, why pay a premium price for an iPod - the coolest MP3 player on the market, and then completely ruin it with a huge plastic case?
iPod skins are the answer to this. Paper-thin, vinyl stickers which wrap perfectly around the outline of your iPod, having virtually no impact on its shape whatsoever. Despite this, they will still protect your iPod from scratching so if you take it off, your iPod will be left looking as good as new!
