From the EFF blog:
With the 2010 holidays upon us, it's time to update EFF's E-Book Buyer's Guide to E-Book Privacy, which summarizes and comments on the privacy-related policies of several ereaders.
What's new. We've added in the iPad and also added in the software used by many libraries and devices for e-book access, made by Adobe called Adobe Content Server. Adobe doesn't keep a list of libraries that use their software, but it does have a list of supported devices. Remember that the list only tells you what information is available to Adobe, not what information may be made available to the device itself. The information about the Adobe Content Server comes directly to us from Adobe.
The really interesting part is that they don't actually discuss the best way to keep your privacy. Pirate your ebooks over a public Wifi. I'm not saying you should, just that it's the only way to really be private.
So what is this, the 3rd or 4th version of their buying guide?
