Apple was screwed when they went with the G5 for desktops and had nothing for mobile use so they have to keep using the G4. Then you have multiple core CPUs coming out for laptops and that ended any hope Apple had with PPC. Was there any work done of dual core G4 designs?

Don't feel bad, even AMD had nothing really to compete with Intels dominance of the laptop CPU. I have a pretty large laptop collection and other then an HP model with a K6-2+ and a NEC V20 Tandy every CPU everything is Intel.
