As a person who owns both a regular old flatbed scanner separately from the keyboard, I can appreciate the importance of having the scanner closer to the mouse.
This Keyscan Keyboard comes with a 4800dpi scanner attached to the top of the keyboard for easy document scanning. I think this is a pretty good idea.
