I just bought a Logitech S715i ipod dock stereo and have had a 3-year-old Apple macbook pro. I was hoping someone made a bluetooth transmitter that plops in the ipod dock that could talk to my laptop via bluetooth so I could listen to iTunes wirelessly without having to purchase a brand new bluetooth stereo. I looked at the "Scosche IPBCK Stereo Bluetooth Connection Kit for iPods," but I would have to continue to recharge it since it doesn't connect (and draw power from) the ipod dock. Ideas?
