I hate the stylus. When I'm using it, I feel I need to "work" with it. The finger is natural and playful. Humans have been using their fingers to paint and draw long before they used brushes or pens.
A stylus is a powerful tool. To require it is folly. You have to create a platform that either ecompasses both inputs or chooses one. Simplicity would dictate the latter, and the finger is just more human.
