Actually, that's just two screenshots from the same Google Play version. A side-by-side with O'Reilly's PDF is striking

We still sell all O'Reilly books DRM free in both PDF and ePUB. i.e. http://www.ebooks.com/95729334/designing-data-intensive-appl.... If you click on preview (on a desktop), the preview is composed of images rendered from the PDF.

>DRM-free

>supported on "e-readers with Adobe Digital Editions installed"

Someone is incorrect here.

Thanks for the feedback, the boilerplate template was wrong. We've updated product description pages so they're clearer now (Clearly states DRM free)

Looking at the info about the formats for that book it seems that the ePub and PDF are unrestricted.

The second statement is probably boilerplate but is concerning.

Yes, you're right, it's boilerplate and needs to be updated to reflect that O'Reilly books are DRM-free and can be read on any device, I'll get it updated tomorrow.

Why does that page you linked have a list of supported devices? It looks to me like ebooks.com does use DRM.

You're correct, it should have different info for DRM free books under the supported devices section. We do use DRM at ebooks.com, but only for the publishers that enforce us to use it (99% of publishers).

I really want to support you, but $42AUD is many times more than it would have cost on oreilly.com.

That seems to be two different screenshots of different parts of the Google version. The typesetting is pretty bad.
