When I was partnered in a small independent imprint, it was felt that you weren't a
real publisher unless you also produced physical print books too. Even though I started with eBooks, we soon set up for actual print, as well and that was very satisfying.
Despite a meteoric rise in eBook sales around 2010, print books now far outstrip their electronic equivalents in terms of sales - (
https://blog.gitnux.com/amazon-book-sales-statistics/) for one such example. I'm not sure why that is, except that fewer people than we assume here have eReader devices. They have iPads and phones, always but I know very few of my friends who own an eReader.
Whilst I love the feel and look of a well produced printed book, eBooks have well and truly taken over for my reading, for at least the last 10 years or more:
Hundreds, thousands even, of eBooks can be stored on the one device; you can alter the size, look and layout of text; well formed eBooks now look as good as their print equivalents; You have a self contained experience, with integral lighting, often waterproofed (though I never read a book in the bath and reading by the pool/sea never destroyed one before either); you can manage, index, arrange your books into any library, you want; you have dictionaries and word look-up, at a fingertip, on the same device; you have a totally interactive reference system, for indexes and links, etc.
I still buy big technical and textbooks in print though and coloured coffee table eBooks are still some way off on E-Ink devices. Most people will be seeing those kind of books electronically on a laptop, PC etc. still for some time, mostly in PDF form.
But for the kind of reading, that paperbacks always involved, mostly pure words, eBooks are almost in everyway better to me, it's almost a no-brainer, for the all of the above, IMHV. So again I'm not sure why the physical ones have bounced back in such force, except, as I mentioned, for dedicated eReaders not being an obvious choice for many.
