|Nike+ iPod Sensor|
I had an iPhone, so all I needed was the Nike+ transmitter. And after I bought the Nike+ transmitter, I realized that there is a $1.99 Nike+ GPS app that works with the iPhone with no transmitter required. Did I just waste $20.00 on the Nike+ transmitter when I could have simply purchased a $1.99 app. Well, yes and no. Nike+ iPod and Nike+ GPS are two entirely different animals that serve similar purposes.
