PowerBook is a quite thin computer. Just 1 inch. And when Apple released MBP, they makde it even thinner: they shaved 1mm off of it. Am I the only one who feels that they shouldn't have done that? Let's face it, 1mm is peanuts. No-one is going to notice it, unless you compare them side-by-side. And we all know that Apple is having some issues with MBP as it is. It runs hot, the GPU is underclocked, and only 17" model has dual-layer burner. Now, making the internals even more cramped by making the machine even thinner, doesn't exactly help in the heat-department. And the underclocking is an indication of that. I also heard that the missing dual-layer burner is because of the thinner enclosure. So, instead if giving us an enclosure that is tiny amount thinner, they could have given us a computer that runs a but cooler and has a dual-layer burner. By making the machie tiny bit more sexy, they sacrificed on actual functionality.
