10 Killer Features for Apple’s iWatch
Wi-Fi and Bluetooth
Every smart watch on the market requires you to pair it to your phone via Bluetooth, which limits its functionality when your phone isn’t around. However, if the iWatch has Wi-Fi (or even a SIM card for a possible cellular version), you would be able to stay connected anywhere. However, in order for Apple to pull this off it would need to integrate a very low-power Wi-Fi chip and make it very easy to toggle this radio to save juice.
