Hop on the internet, do a quick search or visit any sort of design or art online shop, and you'll most certainly find all sorts of "skins" - that is, safe ways to make clean and sleek gadgets like the iAnything or laptop a bit more personal. What you'll also realize is that a "skin" is just a big vinyl sticker, which means it's completely possible, easy, and not expensive to just make your own.
