For short time periods
I've never permanently gone back to paper, but I sure wouldn't rule it out. At times, when I've either grown numb to my system or just needed a change, I've switched to paper for a few months. I never switch my calendar, however; I need that to be electronic. As I was writing out my lists, by the way, I got rid of a whole bunch of stuff. It's really easy to get clutter in an electronic system, isn't it?
I think you need to do what attracts you. If you are attracted to paper, make the switch! If you find you don't like it after a little while, go back. No matter what your system is it will do you little good if you aren't attracted to it!
