I am looking for a display to use with my Powerbook G4 12". I am in love with the 30" cinema display, but according to technical support today, my setup is not compatible (supposedly, but the person on the phone didn't sound to sure). I have a mini DVI, but the 30" requires a dual DVI. I think the 23" display requires DVI, which I can attain with an adapter. Does anyone have suggestions for what I can use with my computer? The bigger the better for me. Also what do you think of the older (plastic case) apple displays? I'm open to all brands and generations. Thanks.
