Apple's newly patented Advanced Stylus won't be used on the screen of any of product. It will be used like a mouse is, i.e. on a desk. It will serve as a pointer, NOT as a Nintendo DS sort of stylus. WHY? Because it's main feature is Pressure Sensing. That means IT senses how hard you're pressing, not the iPad. Furthermore, if people used them on the glass screen of an iPad and pressed too hard, the glass would Shatter.
