Think of it as Bluetooth getting better. You not only get a choice of different colors but can pair three devices without having to disconnect from them. Once you walk out of range of your handset a melody plays, so that you don't have to worry if you loose connection. Although there is some draw backs when using VOIP. It's only a matter of time before they correct it's little bugs. But besides that. It looks like bluetooth is going in a great direction.
