When Bluetooth (short range, radio frequency communication standard for wireless connectivity) first became available, one of the first devices to take advantage of this new protocol was the cellular phone. The protocol was perfect for short range use such as synchronizing the phone to your computer, using the phone as a modem, or wireless, hands-free headsets. I have always been a fan of hands-free headsets. You could talk on the phone while keeping both hands on the car steering wheel and the earpiece made it easier to hear the person you were talking with.
