In fairness, in my own notes, formulas are rare. The only thing close to drawing in my notes is a spider diagram and MindNode is probably a lot easier and friendlier than pen and paper for that. I can probably cover my ground in Photoshop than I can on paper too. Pen and paper just seems to make things 'sink in'. Feels a bit different to being hindered by the tool of choice!
