A bit of a rant - sorry in advance. I'm wondering why in the world Apple wouldn't build in support for nike+ with their shuffle. I'm just starting to get into running and I feel like this little device would help me a lot with motivation, etc. It would work with my iPhone, but really who wants to go running with a 600 dollar device strapped awkwardly to your arm? I see people with these arm bands and think, that just cannot feel comfortable. I have a 2nd gen shuffle, which of course isn't compatible. And, really, I wouldn't even want to run with a nano and an armband - Maybe if the nano had a built in clip like the shuffles do. I just feel like the shuffle is the iPod made for working out, running, etc. It is the least likely to fall off and break, and if it does, no big deal, its 70 bucks. So WHY is it not compatible with nike+? So after all this, my question is, does anyone think this will happen in the near future? Will the 4th gen shuffle have a built in bluetooth receiver for this application?
