seriously? you're not gonna buy any more products from apple JUST because the iPod Nano doesn't pair with an iPhone?
In my opinion, i think that the iPod nano is perfect the way it is, it does its job and it's the 2nd generation of the iPod nano to have a multi-touch screen.
also, if the iPod WAS able to be paired with an iPhone, what would that do? just sync Nike+ data? you also need to take into consideration that the iPod Nano is intended for use of viewing photos, videos, and obviously, listening to audio (music, podcasts).
also, there's not that much RAM in it (i don't know, to be honest, but i know that it's not enough for handling tons of apps like the iPod Touch), so you would most likely NOT be able to get apps.
basically, if you're telling apple to make an iPod that syncs with an iPhone, you're pretty much telling them to make the Watch but in a non-watch form.
why not just get a Watch Sport that's only 399? or buy a normal Watch and take off the wriststrap? it's better than, what most of you are telling/suggesting, an option for syncing a little iPod Nano's Nike+ data to an iPhone
