It's a little bit embarassing to admit, but I never purchased eBooks at all. Only "legal" copies I have are in the form of paper books. One interesting thing, that just struck me, is that my SO the other day purchased one of the books in the form of eBook on one of the "local" online book stores. And from what they told me it's completely DRM free, even though it's something that was written by a foreign writer. From what I know this marketplace does not have every book in the digital format nor it is certain that all of the digital copies are DRM free there. But my guess is that some regional marketplaces might have some legal DRM free content, just not being vocal about this
