Connector Orientation - Can I get a little help...?

Industrial designers these days like things to be symmetrical and "clean" - which gives us (admittedly attractive) simple shapes for buttons and rows of identical switches. But this ignores the human need to associate a unique physical feature with each function - and Lifehacker has a great case in point. A reader of theirs by the name of Jon observes that the Zune cable is symmetrical, with nary an indication as to which side is "up." His solution is pretty elegant: a single drop of superglue, which not only maintains the clean design aesthetic with a durable fix, but gives the connector both a visual and tactile orientation cue. That gives it an edge over the iPod/iPhone cable, even, since those only have a faint graphic but no tactile cue for orientation. Well done - now designers, pick up this trick!
