I end up writing a LOT when trying to prove stuff. I can go through a legal pad in a week for one class -- and the writing is just scratchwork, so it's all trash. That is too wasteful for me, so I got a paper-sized whiteboard, but I am finding that I need a bigger one. How big should I go? Should I just get another small one? Is there some PC program that's as flexible as pen and paper? Has anyone tried one of those digital writing pads? I don't think I want my pen and paper to need a power source other than me, and I might still want more (continuous) space. Should I just mount a big whiiteboard on my wall? Has anyone found a good solution to a similar problem?
