If you ever cared to look at the back of an iPod you must have seen a surface that simply begs to have something engraved on it. Sure, if most cases the engraving will be covered by the case, but it can still be cool to know that there is a hidden message on the back of your mp3 player! Also, although not exactly a method of theft protection, engraving at least assures that a potential thief would have a difficult time reselling an iPod (a laptop, a PDA – what have you) if there is an owner’s name etched on its back. Actually, if ALL iPods had owners’ name engraved stealing them would become almost useless.
I could not find too many details about this one, but the concept is extremely promising.
