"A notepad test: take a pen and a piece of paper or notepad and write a few words or your name. Easy, isn’t it? Now what about doing that on your iPad, but add the ability to carry with you many pens and paper types, preprepared perfect shapes, highlighter pens and a virtually unlimited reference book that you could cut and paste from (the Internet). Sound a little bit better than the pad and pencil? You’d like to think so."
