From a business perspective it makes sense to have your book available in as many formats as possible and distributed as widely as possible. While ebooks, especially Amazon's Kindle, have been a huge boon to self-published authors, it makes sense for several reasons to offer books in POD print editions as well.
First, it would seem the so-called "digital natives" prefer to read books in print over digital ebooks by a considerable margin, especially when reading for pleasure. Of course surveys that conclude this type of results are controversial, particularly among the serious adopters of technology. Reading the comments are sometimes as informative as the actual story.
Then there is the issue of whether or not we should be creating "digital natives" before their brains have matured physically. As a high school teacher for the past 30+ years, I can assure you the reading ability of the average student has made a serious decline.
Others simply argued any evidence I had was anecdotal and could not be validated. That is until brain researchers discovered all the digital usage by today's youth has in fact changed how their brains develop and not always for the better. One of those negative effects has been a serious deterioration in the brain's ability to process written language.
Given the fact school administrators have moved towards digital textbooks, and with good reason when you see the amount of money spent on textbooks, this is bound to be a controversial topic in the coming years.
As a school teacher and grandparent, this topic is of great interest to me. To read more, click here.
