Safe driving, you keep your hands on the wheel. You don"t have to choose between your personal and business phone anymore. Portable, you can carry it from a vehicle to another. You say "OK" to pick up the call, so you don"t need to remove your hands from the wheel to press a button. Multipoint: two phones connected at the same time (personal and business phone for example). Automatic reconnection between your phone and the Supertooth One when you go back into your car.
