Noting that the interaction you are accustomed to using a Wacom tablet is far more controlled and rich, I don't think thats the point here at all.

Every artistic medium has constraints, and every artist is used to this fact whether he is a painter or a sculpter. The iPad's input device (capacitive screen) is one such constraint here. What I think is great about this app is how great it can be at capturing a good number of important expressive pieces that are possible in the medium and presenting them as easy to understand tools. In using the app for about 30 mins I felt pretty great about what I was able to create in comparison to other apps on the same medium (iPad apps).
