Hard Copy for the win. One, it makes you look smart in public, Two, Do not rely on technology. I always try to write all of my important notes down instead of having it on my cell or computer. Three, I feel like you concentrate more on a hard copy then on a tablet or the computer. I think it is because of the brightness of the screen. That and that you have the lingering distraction of opening a new page and "checking your email" or "going to facebook".
