One thing that would make ebooks shine would involve the copyright-holders of long-out-of-print books making them available as ebooks. It takes a large anticipated market to justify a print run. A book can justify its electronic existence on a server disk with just one purchase per year.
I think they are already halfway there.
If you do a search on some of the more popular older books, you’ll get a return of many print-on-demand books.
That means they’ve digitized those older books and are ready to print.
Why they don’t create a pay site and make those books available for online reading or download is beyond me.
