P-BOOK VS E-BOOK
This Debate is still going on! In my view, It is just a proxy for the Analog vs Digital debate, in case of Books.
If the Analog-Digital dispute ceases elsewhere (viz. in Music, Movies, etc) favouring the Digital and yet lingers about the Books, that does not — by itself — mean that the Analog will survive (at long last) in the world of the Books. It might be just that the Books change their medium as quite the last candidate.
One significant factor in this Debate is that, which angle do you see this debate from? — From the Consumer's side or the Producer's side.
Consumer might only focus on the sentimental and certain aesthetic values.
But the Producer might feel the fear of its sale-ability at the same time. Because of Online Piracy.
Since p-book has no technological defense against this Modern piracy, i.e. the mass of some paper & ink can be blown away today (via a scanned PDF file) into a light energy media in terms of giving the same Info, there is practically no cost of obtaining a soft-copy of the same book. I call it e'-book. (Not an original e-book, but a scanned electronic version presented as the corresponding e-book.)
If there is no Draconian legislation followed by its strict implementation ever available in a country, which in turn necessitates updating the last millennium's Copyright laws & proper monitoring system, people might just tend to obtain practically FREE e'-books instead of the p-books. Which would supposedly be priced as high as, at least, their OVERHEAD COSTS (production cost + distribution cost).
So if the FREE wins, p-books lose their appeal to the Producers' community. But if a Consumer gives guarantee that the COST will be paid, then the Producer can go for the p-book.
Thus in this angle I think, p-books in these countries will have no commercial risk if and only if they are produced in the realm of POD (print on demand) basis.
