I used a Surface and OneNote. It sounds silly, but I can draw maps, illustrate scenes, use scratch paper, make notes, plan encounters, literally everything with just my tablet and a pen. Plus, I can hook up to a TV or monitor and show my players things all while keeping the other things I've written visible to only me. It's incredibly useful and I can't imagine going back to gaming without it.
