On the other hand, an electronic notebook has infinitely large pages, easy cut & paste, ability to zoom in to work on details, and you can repeatedly erase stuff without any smudges. By moving stuff around you can easily rearrange the structure of your notes, and add lots of new stuff in the middle. You can carry around tens of thousands of pages on a single light-weight device. Electronic systems with OCR may also have usable search. In other words, it's a trade-off.
