Just to forewarn you, this is going to turn into a piracy thread...
Camp Arrrr: If it's not available as an ebook, I will simply pirate it. Author is refusing me something I want.
Camp Middle-Ground: I'll buy the pbook, then pirate the ebook. Author still gets paid, I get what I want.
Camp Angel: It's the author's right not to sell you a book in e-format. Forget about the book and move on to something else. There are plenty of other ebooks out there to read!
Did I cover all the viewpoints?
