I had a desktop computer at home I used for serious work, typing papers, making power points, etc, and an iPad I took to classes and clinicals with me. I had all my books downloaded to my iPad through the Kindle
app, and downloaded the lecture slides that were posted on line through Dropbox and took notes on them with a stylus through an app, Notability, that's sadly not available anymore. Then I had all my notes and books readily with me wherever I was. I know there are also note taking apps that will record audio as well as you take notes.
I downloaded the Mental Case app, as did many of my classmates, and we made and exchanged flashcards to study.
I used apps like Epocrates, Diagnausers, and the 5 Minute Clinical Consult at clinicals all the time.
My iPad was an invaluable tool for NP school. Anyone who says it has no purpose hasn't looked into all the possibilities. You do need a real computer available to you as well, though. I bought a bluetooth keyboard for my iPad and have typed more than one paper on it in a crunch using the Pages app. It's doable.
