1) On the website, the 'Nike + iPod' sport music is advertised and suggested ... but can you use Nike+ with your own music? 2) Is Nike+ the same on both the iPod touch and nano? Or is the version on the touch better? 3) Is the iPhone supported or will it be? 4) Are the Nike+iPod armbands fun to use, or will I be better off by simply putting the iPod in my pockets? 5) Any final things you want to add yourself?
