Ipads are not the solution - that gets you back to screen/computer mode in the classroom.
e-readers/ e-paper tablets might be worth a try. (Just please don't make every child have a mandatory amazon account to link with their school kindle.) It would be interesting to know whether the "books+hand notes > screens + typing" comprehension studies have something to say about e-paper (I don't think this has been done yet).
My own experience, even to this day, is that it's easier for me to learn a new language or technology from a book compared to on a screen, even if the digital version lets me work on actual code: if I can, I first read the book and take notes, then I do the online version.
