Three-by-five index cards, those hallmarks of research, may be fading away in these digital times, but the need to take notes endures.
Human memory is as weak as ever, and people are still shoring it up by recording their observations, research and grocery lists, though many now use computers instead of pens and paper.
But the electronic notepads on smartphones, tablets, laptops and desktops don't synchronize with one another automatically. Say you're sitting on a plane with your laptop, jotting down some brilliant words for that speech you're giving next week. Back at the office, those notes will never find their way to the copy of the speech you've stored on your desktop, unless, for example, you e-mail them to yourself.
