I have one on my G3 800m dual usb ibook and it works great. I bought mine used off ebay and the gentlman sent me the dongle and a cd with the driver. Only thing is I have to unplug it each time I shut it down and I have to wait for it to boot before I plug it in but big deal .I use it with my Motorola wirless G router and at school and it is as fast as my wired windows machine.
