eh, writing on an iPad is kind of awkward, much faster to just write on paper..... i took grad classes at duke and some people would try and type everything on their computer that they could possibly type, and never looked up at the lecture but had everything typed... some would have their iPad/tablet, and they would always get behind on note taking, or just use it to view the power point slides which is pointless because its projected in front of you... and others would actually pay attention and just listen to the lecture and jot down things they deemed important...I just recorded the lecture on my phone and paid attention... but yeah taking notes on an iPad seems great in theory, but its just not that great in practice... at least for me and from what I have observed.... I don't know for the classes I took, almost everything came from journals so you could always just go back and look at the paper they were referencing... its so much easier than undergrad.... no memorizing, just applying things and making rational arguments.... you also have to consider that for some classes you are just discussing literature, and not like taking notes on a lecture etc....
