Peter Svensson reporting on the iPhone 4S and the bluetooth tech Apple packed inside:
>The phone, which went on sale Oct. 14, is the first one to have a new type of Bluetooth chip that can connect using very little power. The chip uses so little power that it can go into devices that are powered only by a standard “button cell” or watch battery.

He notes that this allows communication with devices like watches, glucose and heart monitors — pretty neat.
