I'm a college student. I both do artwork on my iPad and take notes in class and have hundreds of dollars in styluses I have tried out through the years in my desk right now.
I'd love for Apple to include pressure sensitivity in the iPad screen or create their own stylus that adds pressure sensitivity with a fine tip that is not half baked and also beef up wrist guard protection throughout their OS.
I'm sorry Steve Jobs and his fanatics but using only a finger to product sketches & notes, even over a short period of time (let alone the hours spent in a classroom) doesn't work.
I think Jobs and his dislike of the stylus is for the touch screens of the pre-2007 market, when most were resistive touch screens. Nobody would have used an tablet to make serious art back then. Today, if he were still alive, he probably would green light the stylus.
