The 6s Plus particularly seems well-suited for note-taking of all types. With the ability to sketch (with 3D touch!) and type comfortably I see it as a great device for the classroom. I know personally I would be much more inclined to study my notes and create great notes if they're electronically saved. Who has experience with this in the classroom? I'm sure some teachers would initially frown upon a classroom of kids using their phones but I see no reason to carry an iPad or a tablet when I already have a capable iPhone in my pocket other than for productivity vanity.
