Wow, thanks for that list, in particular for Simon & Schuster. I am a Trekkie (that's the origin of my handle, too), and I sometimes bought Star Trek e-books on Amazon (most recently, Department of Temporal Investigations series). I'd much prefer to buy DRM-free.

> I don't mind watermarks, I ain't a pirate

That depends; pirates mind water marks on goods they liberated on the high seas, as they reveal the provenance of the merchandise. They like the marks left by water on their equipment, as a proof of prowess.

(Yes, I had to.)
