Nike + Air

I started reading Shape Magazine and I have come across this on tv and on the Internet, but I am curious if anyone is using or running with the Nike + Air in your shoes, linking to your nano, & updating to the community on Nike?

I am very near getting on board, but am just curious. If I follow through and do this I will blog more on my experiences with it. I think in the next few months I may try it as the weather gets nicer and I can get outside and exercise more.
