Whatever the rationale: People will pay what people are willing to pay. If the price is too high, competition should bring it down. The price clearly wasn't too high.
When I purchase a book, I decide how much I'll pay based on what the book will do for me. I'll get the same entertainment/info whether it is printed or electronic. For some types of books I prefer printed, so I won't pay much for the ebook. For fiction, I prefer electronic (already have too many physical books in the house), so I'll happily pay for it.

Of course, smart people just use libraries :-)
