@danskmacabre: Sorry if I sounded like a jerk. I'd just read that whole Terry Goodkind thread. I didn't mean to make it sound like I was accusing you personally of pirating books. My point was that if someone had committed some other crime and were to have secondhand ebooks on their hard drive, it's not such a stretch that the DA might use them as a reason to give someone grief.
I've never said that changing the format of a purchased DRM'd ebook for personal use was a big crime, though I've never done it. But to change the format and then give the book to someone else, well, that's shady and could see someone getting in trouble for it. You'd basically have to take off any DRM to be able to hand say a Kindle book off to someone else because they're tied to your Amazon account.
BTW, I used to think the spread of my books was good advertising and at least one person had to buy it for all those copies to exist, but that was before I realized how sneaky some people are. They buy an ebook on Amazon, copy it, then return it for a refund. At least with a paperback it's time intensive to scan it and reformat it, plus there's something nice about the feel and smell of paper
