I think it could be pretty useful, but unfortunately I do not enjoy it as much as I could. The reason is, however, do to the nature how the iPad works.

My problem is, for example, when I want to draw a rectangle on a grid, I always loose drawing precision, because I don't see what is under my finger - naturally my finger is on top of what I actually want to see to be precise. I think what is really necessary is something like a zoom-popup somewhere in the upper right or upper left corner that shows exactly the region that I don't see because my finger is on top of it. Otherwise, it will always be painful to fix the elements that aren't quite right due to that problem.
