Handheld scanners

I've been agonizing for sometime about getting a device that will let me capture both text and images in archival (controlled) situations. I don't want to lug a laptop around and obviously cannot feed ancient manuscript pages into a sheet scanner; neither can I use a tiny beam/flashlight type scanner favored by my brother-in-law to go through rare books line by line.

This seems to be the answer and it seems to have no counterpart in the market. Have a look.
