Why would I want the keyboard and the other stuff in the same height in the first place? I touch type and that's better with the keyboard slightly below elbow height (in order to keep wrists straight while typing). That's not the case with handwriting. Of course I have the keyboard on a tray or in my lap, thus lower, while printed material is in my field of vision, thus closer to screens. (Ignoring the fact, that I prefer to use a pen-enabled tablet (i.e., a graphical tablet or a Tablet PC) for handwriting.)
