I just purchased an iPad for general use and for taking lecture note. I've broswed the forum and haven't really seen a good answer so I'm going to ask here: What is the definitive note taking application and stylus for writing? I basically want to go into a class, pull out my iPad, start an application, have my notes sorted by course and perhaps date of entry or something, and just be able to write, save my note to its appropriate class, and move in. Sorry if this may seem redundant. Also just generally excited about my new purchase.
