Hell, thats a minor bug. Check out the threads about dual monitors and 1.5 gig of RAM. We cannot even run the installer. It has a kernal panic when there is a Radeon card installed for a second monitor and hangs giving the newly daubbed "grey screen of silence". If you pull the card you can install, but the machine will crash as soon as you put it back in. Not too sexy considering that alot of Mac users are graphic professionls.
