It really is... I sync my Nike+ to an iPod Touch instead, so I can't use it myself, but if I had a Nano I'd definitely get it. The Nike+ sensor sends info about your workout to your iPod device to help you design, monitor and track your workout. The Touch fits into a sleeve on my arm so it's not too bad that I have the earphone wires connected to it, but it I had to connect those wires all the way to my wrist that would be a pain. So the fact that the music and data is beamed via Bluetooth to your headphones, I think will allow this product to take off. Hopefully it won't be undercut by cheap knock offs from China.
