I don't see that there is a significant difference between ebooks replacing paper books, and books replacing scrolls, or mp3s replacing CDs replacing vinyl. Aficionados may still use the legacy format, preferring it due to some special advantage, but for the normal man-in-the-street, the more convenient format will definitely replace the old. Pop-up books and textured books for small children, like the "That's not my ..." series are a different matter, and I can't picture quite what their replacement will be; but normal story books, whether illustrated or not, will easily be replaced by ebooks, once colour e-ink is good enough and cheap enough. I don't think it will happen to you or I in our lifetimes, we already own too many books, and the effort and expense of replacing our existing paper collections with electronic copies is too great. It will happen to other people in our lifetimes. People who are young children today are just as unlikely to buy paper books in adulthood as today's youth are to buy CDs. I wouldn't be surprised if your son's high school studies are conducted without paper books. I can't imagine buying paper fiction for myself any more, unless I have a very good reason for doing so (I recently had to kill several hours alone on a rainy day with nothing but my wallet, so I bought one).
