Resolution and aspect ratio are two different things. Comparing 800x600 to 800x480, without mentioning the pixel density (ppi), really tells you nothing execpt the aspect ratio.
http://en.wikipedia.org/wiki/Display_resolution
"Note that the use of the word resolution here is a misnomer, though common. The term “display resolution” is usually used to mean pixel dimensions, the number of pixels in each dimension (e.g., 1920×1200), which does not tell anything about the resolution of the display on which the image is actually formed: resolution properly refers to the pixel density, the number of pixels per unit distance or area, not total number of pixels."
I wish mfgs would include ppi in their specs but they hardly ever do. I guess they don't want us to be able to know that gadget A has a sharper, crisper image than gadget B.
