The new Macbook Pro has a 15.4" screen compared to the old Powerbook. And yet the powerbook has a resolution of 1440*960 as opposed to the new 1440*900 Macbook. What gives? I understand that the new display is some 60% brighter, which is overall more important for the quality of the display than the resolution, but I don't understand why a size increase should come with a decrease in resolution. Is Apple getting the display from a new supplier or something? Until they add a 17" model, this is definitely weird.
