But, some people, need more precision than a human finger allows. They use an object with a finer point than our fingers. But, the rest of us are okay with just finger painting. The paper was designed to be large enough for fingers to use.
It would be nice to sometimes use a different input method on paper when the finger won't cut it. I see nothing wrong with having more than one input method. There is no right or wrong way.
Ship it without a stylus. Require that all apps be usable with fingers. Make a sweet pressure-sensitive stylus available for extra precision. Everyone wins.
Here's the thing, it's not the stylus that is the problem. It's the dependency on a stylus. There is a difference between doing it, and doing it right.
