HI, I have an iMac g4 1.25ghz with the incredible 20" screen..just love this machine! However I'd like to use my mightymouse and a wireless keyboard with it... Do any of you have a bluetooth dongle (or internal) working well on your G4? I'm not sure which one to buy, I want something that works flawlessly... Let me know if any of you guys have suggestions. Should I just go with the cheapest one on ebay? Thanks!
