From the rumors floating around about the (possible) new Treo, it is supposed to have Bluetooth capability. Right now I have (in addition to my 300) a Dell Axim that is wireless that lets me access mp3 files from my home PC. What capabilities will bluetooth get me and will it let me do what I am doing with my Axim (which I hope to do away with), that is play mp3 files from my home computer while in my house.
