The interesting thing about drawing on the iPad is its complete lack of paper friction. It actually took me by surprise. My first couple of drawings looked as if someone else had done them. It was like the guardrails were off and my pen kept going off the road. I finally got past that by concentrating on the actual line being created and not relying on the paper tension to rein my pen in. I enjoy both mediums, but they are definitely two completely different animals.
