for as high techie as I am, I didn't even really KNOW much about
   bluetooth 'til my brother wanted one about 2 yrs ago. Before
   that, I just didn't pay it much mind. I knew it was some kind of
   wireless thing. Now we have a bluetooth stereo transmitter in
   the barn, so anybody can play songs from their phones / ipod
   touches over a 1970's high power stereo system with super Tim
   speakers. "
