It's a tool like anything else. If you use it right, it can allow you to do certain things better than you could on paper. I used an iPad to take notes on PDFs of lectures and textbooks when possible. Was incredibly helpful, and searching worked faster than flipping pages. The stylus is very accurate as as easy to write with as paper. Eventually found an app called Notability to takes notes that stayed in sync with audio recording of the lecture. Helped a ton concentrating on what was being spoken instead of trying to transcribe it, and revisiting areas of confusion.
