Some flatbed scanners are light enough to carry around, but even the smallest are larger than a notebook PC. Planon's DocuPen RC800 is a portable pen scanner that's easier to take on the road. It weighs under 60g and is as long as a sheet of A4 paper is wide.
".even the smallest desktop scanners need to remain, well, on your desk. The DocuPen is a portable pen-size scanner that can hold up to 100 pages."
