It's because Incredible, Nexus and Desire "cheat" a bit on the resolution. While they all have 800x480 in pixel count - not every pixel has R, G and B component. In fact, each pixel has either the red and green or the blue and green. So, when you count the actual numbers of RGB pixels, its resolution is more like 653 x 392 resolution, while N900 has a true 800x480 display and looks sharper.
