*Height: first number is with URL/Toolbars, second number is "app view" size without them. On Honeycomb devices browser has no "app view" mode, but 3rd party browsers (like Dolphin) have a "fullscreen" mode that achieves the same effect. Also note that on Honeycomb devices the @320dpi the pixel sizes are the same as @160 dpi so when high-density devices become available it is likely content will simply be scaled up 2x as it is on Apple's "Retina" display.
