ETA: Appears the D4 has good sunlight visibility, but not sure how it compares with N900: "Yes. The "blurring during vertical scroll" is a reported "feature" of the D4's pentile display. There was much griping in this forum early in the D4's release history about that. It seems that we've mostly gotten used to it, although it still bugs me a bit when I notice it. OTOH, I believe the pentile display is better in sunlight (for instance, compared to the Samsung Stratosphere, since you mention it... my wife's using one of those, and I can use my D4 outdoors in lighting that completely washer her display out.)
