Bluetooth has security built in.  You have to "pair" the devices the first time they connect to
allow the connection.  Don't ask me how good the security is...I don't know.  But I don't hear much
about bluetooth hacking, so I assume it is reasonably good for most users.

Another example of the uses of bluetooth: many cars now support bluetooth phones. Once they have
been paired, calls to the phone are routed (locally via bluetooth) to the car audio system. My car
mutes the audio when the phone rings and I can answer by pushing a button on the steering wheel. I'm
then on a speakerphone via the car audio and phone integration. I don't use the phone much, but it
is pretty slick on those few occasions I've used it. I'd use bluetooth audio integration MUCH more
often, but for reasons I cannot fathom, the car doesn't support that :(
