One of the biggest gripes of smartwatch ownership is the (usual) dependency on your smartphone; do you really want to carry two devices when you're going out for a run? If you're an Android Wear fan, you won't have to in the near future. Google tells CNET that "several" updates are coming to its wearable platform before the end of the year, some of which will let you cut the figurative cord. Bluetooth headset support will let you put some music on the watch to listen at any time. GPS support will let you map your run while leaving your phone at home, although you'll logically need a watch with position tracking built-in -- in other words, don't expect it to show up on your early G Watch or Gear Live.
