I'm going into my junior of college and I already have a rMBP and was thinking of purchasing the 9.7 iPP for note-taking and in-class usage. I currently have to take my laptop in addition to notebooks for some classes and it honestly is a pain. Would it be more useful to get the iPP or the iPad Air? Is it worth it to splurge on the Pro (and Pencil) or should the Air suffice? Thanks!
