In any case have you heard of any individual choosing not to buy a book because it didn't have DRM? I have heard of the opposite case.

I have to agree with this. Most readers I interact with (mobilereaders nonwithstanding) don't even know DRM exists. This makes no sense to me at all. I'd have to believe that the non-drm'd books had something else in common. Not that it matters as it doesn't change my stance on the topic, but it makes me a bit more suspicious of the entire report.
