Exactly, this is an ongoing debate. I think everyone does think that the powerbook overall is better than the ibook, but thats not really the question. The question is: is it $600 better, and the answer is no. if you weigh the two primary factors, chip speed and ram. this only diff is .13 ghz. So unless DVI is and absolute necessity, I don't see how anyone can justify that extra $600 for the powerbook, for what is simply a marginal increase in speed, and i'm not simply referring to the processor speed. You get more speed, but not $600 dollars worth.
