<i>Because DRM ebooks from Amazon tend to be delivered in an incrementally more convenient way</i><p>I&#x27;m not sure how DRM factors into this. I buy ebooks through Google all the time, and only a minority of them are DRM-protected. Yes as far as I can see, the distribution mechanism is identical whether DRM is in place or not. My understanding is that &quot;put DRM on this book&quot; is nothing more than a checkbox that the author chooses for the book.
