There can be good reasons to use the px unit, even though they should be pretty rare. AbsoluteLayout was deprecated to encourage developers to use other layouts and have apps that behave as well as possible at difference resolutions.
Also, the dp unit depends on the density of the screen, not the number of pixels. AbsoluteLayout is a problem as soon as you change either the density or the screen resolution. For instance, if you go from 320x480 (G1) to 640x480 but keep the same density (about 180 dpi), a layout defined with AbsoluteLayout will not work properly. By using a LinearLayout for instance, the layout will at least adapt to any new screen resolution. It might look too big or too small if the density changes, but at least it would be using the screen estate correctly.
