By owning a Surface RT, I've used OneNote for almost a semester now. For me the only minus side of OneNote is that the PDF slides from the lecturers can't be editable inside OneNote. This is because the things that are "printed" inside OneNote are images which makes the OneNote file big. But then, after trying some alternatives, I cannot find any better one. Seems that I will stick to OneNote for now.
