Apple said that they were trying to do so for a long time by now, and I heard of a chip called POWER7 (Not sure if it's PowerPC but I'm pretty sure) running in a laptop. I even heard somebody say (like 6 years ago) that Apple's shift to Intel would be temporary(I was skeptical of that). I mean, those G5 iMacs were good computers. I always thought that if Apple could've found a way to make a G5 notebook, the performance would've been okay even for today's standards, even though I guess its performance would probably be more like something you would find in a cheaper laptop. I'm not saying that they should've or that it would've been better, just wondering.
