Well, one thing about this machine that I find a pain-in-the-behind is that all the boot disks such the TechTool CD and DiskWarrior CD (as well as the TechTool eDisk) will no longer boot. All you get is an international symbol of the circle with the slash through it. I guess more updates will have to be forthcoming (or, the companies involved stating that they will no longer support new Apple releases). I just wonder what is in the system that is on the new Panther disks that is so essential that the machine will not boot without it! jg
