June 23, 2011: SHOCK: Harry Potter eBooks DRM-FREE!
That was the hype. This is the reality, today:
Confirmed: Harry Potter eBooks Are NOT DRM-Free in Kindle Format (Or Any Other eBookstore)
I’m not buying them. I have no interest in them.
What I want to know is, if someone gives up their Kindle and switches to ePub, can they still download the ePub from Pottermore — where it is DRM-free?
As for the watermarking done on the Pottermore editions, I’d like someone to unzip the ePub and let me know how they’re doing it. I suspect something in the CSS or another exterior file.

Yes you can.
