I was back in university doing a 4-month course earlier this year, and had the opportunity to use my iPad Pro (2018 11" model) for taking notes. The summary was that the various apps at my disposal made note-taking fun for me, but it also resulted in my notes being spread out across multiple different apps, which can make it a hassle to remember where they are stored, much less retrieve them at a moment's notice. That's the main advantage of a physical notebook - it's always faster to flip through a couple of pages then open an app and try to recall the name of the document.
The other drawback of a tablet is that it can also serve as an added source of distraction. Sometimes during a boring part of the lecture, I find myself starting to browse the web or my news feed (between Apollo, Tapatalk, Ivory and Reeder) and message my friends (via telegram).
I used freeform in the first week when the keynote lecturer was sharing the big picture of the leadership course I was attending. The (near) infinite canvas was useful for putting everything together, though it made my iPad lag towards the end of the week as the file got larger. I also have no idea how I am ever going to export it, but it does look pretty (to me at least).
When reading lecture notes, Mindnode was handy as a mind mapping tool for me to list out the main points as I came across them, so that I could try and find links between them later. This was invaluable because it had been over 10 years since I graduated from university, and my brain was struggling to process the academic readings that I was tasked to review prior to each lecture.
For lectures, I either converted the slides to pdf documents that I annotated in the files app (as they were stored in OneDrive), or typed them out in notes. This was where stage manager came in handy, because I could have files, mind node and notes open in front of me (one for the readings, one for note-taking, and one for the summary of the readings). I seriously have no idea how some people are able to follow the lecture armed with just a notebook and a pen.
And if you ever need to present or showcase what you have done or learnt, having it on your iPad is always more convenient.
I say go with the iPad. 😬
