So, some of you may know that I upgraded phones recently. In that deal came a harman/kardon BT speaker. My son's TiBook does not have bluetooth, so I got him a dongle (just like the one for my QS, but with shorter range) and now both his TiBook and my Quicksilver can use this speaker. This is what I love about Apple (most of the time). Two early '00 computers using a 2015 BT speaker!
