The only Mac I have that I would be able to do that with is a first-gen 12" PowerBook G4, and I don't feel like ripping hard drives out of either system. (I do have a spare 2.5" hard drive, but my only external case for such a drive is USB, and since both machines are USB 1.1, the disk cloning would take FOREVER. (I've done it before, that exact thing: Clone the PBG4 onto the external, then clone from there onto the iBook.)
