I don't think the majority of people need or even want smart watches [1]. However an iterative update to the Nano to include Bluetooth 4 connectivity would allow it to be used as a portal to say, the entire music collection sitting on the device in your pocket/handbag, email notifications, weather forecast, Airplay remote etc. So a seemingly pointless ~1gb device becomes a whole lot more desirable through a relatively cheap and simple hardware update. [1] Just another bit of kit that you have to take off/put on each day and doesn't add a whole lot more value than carrying a phone in your pocket. Separate devices are an antithesis to the smartphone - the Swiss Army Knife of the digital world.
