Are the displays of these 2 models different? In the store I thought colors on the ibook looked "washed out" compared to the powerbook. The guy at the store said that the pb had a higher resolution but later I checked the specs and they are listed as the same (maybe the pb has a smaller screen and smaller pixels? either that or the guy was just wrong). I don't think a resolution difference accounts for the washed out look in the ibook display, though. Any thoughts?
