I have been re-learning some trigonometry. What I have been doing was to take lecture notes on one notebook, then keep all my practice work on another notebook....but there is too much page turning, etc. I also have a lot of practice problems, some of which have mistakes, etc. I want to be able to keep all of my good practice problems and lecture notes together...this isn't really possible with physical notes without a lot of stapling, etc. I would like to be able to organize all of my stuff after it is done so I can find what I am looking for. I have been considering something like a wacom intuos....has anyone done digital note taking? There are actual pens and paper that look normal but transmit what you are writing to a computer as well. I would assume that at a normal price point, the input devices will more or less be the same, it is more the software that would probably be the most important. I am not planning on using this for artwork, just writing.
