>The print version of Two Scoops of Django 1.5 has been by far the most popular version of the book with readers, selling several times more than the e-books. In addition, the feedback we've gotten has been that technical books are generally better to have in print than as an ebook.
>Creating and proofing each ebook format is not a trivial effort. It involves reformatting every code sample to work on every ebook reader, accounting for differences in screen contrast, accessibility testing, and proofreading the text and code samples several times on each device. Instead of spending our time struggling with reformatting, we're choosing to focus on improving the technical material.
>Considering that we publicly offered a free electronic copy to those who requested it, seeing piracy of the electronic editions from the first day of sales has been disheartening. As indie authors, it hurts to see this happening.
Now I don't agree with those reasons. I prefer an ebook version as I can bookmark it, make notes, read it on my phone etc. But they have their reasons. It's not going to stop piracy and I might purchase the paper copy and then download one of the pirate versions that will come out. I would prefer they offered a free ebook version that they didn't spend time fixing the code layout issues they mention. The book exists as an electronic version anyhow when it goes to the publisher so it wouldn't be a big deal.
