Maybe you don't realize the folly of selling people on a stylus on a tablet like it is something new, when they are already available as options for the iPad and other Android tablets. You can find tons of stylus options for both platforms. It was a really stupid selling point by Samsung is my point.
Not all styli are created equal. The ones you're talking about are more pointed than ones finger but they are still capacitance-based which makes them much less sensitive than styli for digitisers. They also have no controls or HW features in the stylus the way the Galaxy Note does. For example, it can register pressure to mimic how a pen, pencil or even a paintbrush changes the ink's output based on the pressure being applied.
