Hi, I am getting tired of the unresponsive keyboard which came with my iMac and am wondering if anyone has any experience with USB to ADB adapters like the Griffin iMate. I have an Apple extended keyboard from an old machine that I would love to use in place of the USB model, but before I buy an iMate I would like to hear from others who have used it. I also wonder about the mouse. Is it possible to use the ADB mouse as well as the keyboard with the iMate? If I stick with the original USB mouse I will need to use the USB hub I bought but never have hooked up. Should the hub combined with the iMate work OK. Thanks, Greg
