i am looking to add bluetooth 2.0 and usb 2.0 to my powermac G4. i found some very good prices for both items at newegg for $30 + shipping. the main reason why i want bluetooth is so i can use my LG phone and use a wiimote or a ps3 controller in the future on mac osx 10.4 also how many devices can one bluetooth usb dongle handle? i would like to have a bluetooth keyboard an mouse aswell is this going to be a problem? will i have to buy a dongle for each accesory?
