I've seen reports that research work is being done on various types of 'reading tablet' that would aim for a look and feel somewhat like a convention book, but which could upload different titles. I suppose a memory of some kind and the ability to display a single page would be enough. But it would probably have to feel "booklike" enough to win over conventional book lovers.
I also seem to remember talk of 'electronic paper' which I think was some sort of plastic film that could display type that could be erased and replaced. I think the idea was to stay even closer to a traditional book.
Perhaps this might open more possibilities for "interactive fiction" with the reader taking a small part in the narrative (rather like with games) and either influencing the outcome, or at least feeling involved to some degree?
Would you welcome such developments or resist them?
