The interface for iPhone and a lot of iPad apps would not benefit from a stylus. Buttons are huge. That Samsung device has teeny tiny buttons which requires a stylus. There are only two things I think that can benefit from a stylus and that is handwriting (do we really need to do this? It's slower, harder to read, and very constrained on a small device) and drawing (probably only necessary on iPad). Styluses also require you to hold the device in a new way. No more one handed use. You have to hold the device flat on a surface or in the palm of your secondary hand while you use this stylus in your dominant hand to point. Also, unlike a pencil or pen on paper, the small screen will not allow you to rest the side of your hand on a surface. I can't imagine how tiring it will be to keep your hand in this position for more than a few moments. I think you're mistaking something being different and temporarily fun to explore from something actually being better.
