My split is reference/search (ebook), entertainment/immersion (ebook) and education/assimilation (paper). Ebooks are still too undifferentiated and featureless for effective learning. For example I can often remember that a definition or philosophy is in a large green book with an illustrated cover, 3/4 of the way into the book, on the bottom of the left hand page, author's notes in the left margin, citation reference in the bottom margin, smell of the page, paper color, font, initial cap size on the paragraph. That hooks into my recall and keeps the book interesting while I memorize it. Ebook formats lose a lot of information.
