iPod + Nike = WTF?

Ok, so I'm all about getting more and more nifty little gadgets thrown together to do more fun stuff, but I feel like this is somehow just wrong. Why does the iPod have to be the vehicle of innovation for things which would otherwise be probably very useful? I suppose such is the nature of development: the ubiquitous product becomes the flagship for development. But I would like to register my distaste here and now: the iPod has no business interacting with my sneakers. Period.
