I just bought my wife the mac mini. I am using a 20" Apple display, (aluminum), with my Powerbook. Is there some sort of an adaptor that I can use to have the display connected to the mac mini and the powerbook, without unplugging it. I will not be using them at the same time of course, but, I do not want to have to unplug the connector to switch between the mac mini and the PB. Thanks!
