Hi folks. My mother recently indicated that she's considering being in the market for an ebook reader. However she is, bless her soul, firmly insistent on open format, DRM-free, and the ability to "really own" a book she's downloaded. She doesn't even want the potential for a Kindle-1984-type remote-wipe or an inability to move a book to another device later. (Yes, my mother has grown up to be a Free Software evangelist. I'm so proud of her. *sniff*) Of course, she doesn't know the ebook market all that well, and frankly neither do I. She's considering the B&N Nook, but from what little I know it has the same lock-in problems as the Kindle. So my question is, I suppose, two-fold: 1) Are there any ebook stores or services available for any device that don't treat customers are criminals waiting to happen, and use a DRM-free format without revocation ability? Are they bound to a given device, or are there any that work on an arbitrary Android device? A good ebook reader app or use of the open ePub format (for which I understand there are several readers available) is a plus here. 2) Of the various devices out there (both phone and non-phone), which make particularly good ebook readers? She has a decently large purse but it still wouldn't hold an iPad-sized device comfortably, but at the same time a 3-inch screen is not going to work for her eyes. (It barely works for mine.) What's a good device if that's your main interest? Any good/bad experiences here, or at least things to look for? Help a freedom-loving lady out!
