So most major stores use Adobe, not none as you say.
B&N do not use the standard Adept DRM that other Adobe stores use, which is why many readers cannot read B&N books. So Sony (if you count them as a major store), and Kobo (for non-Kobo devices only) use the standard Adept DRM. Vs Amazon, Apple, B&N and Kobo (for Kobo devices) that do not. 1.5 for, 3.5 against.
By %age of books sold, an overwhelming proportion of the market do not use standard Adept DRM. Even excluding Amazon and sticking just to ePub books, this is still true. This is hardly surprising, why would they want to pay Adobe 22c per book sold for something that a major player could instead do for themselves?
