> Unfortunately, in order to use a non-Kindle application, I have to buy DRM-Free books No. All you have to do is own an old Kindle (buy one on ebay if necessary). Then you can download DRM protected Kindle files from Amazon for this old device, and Calibre and the appropriate plugin can un-DRM them, and transform them in any other format (epub, mobi, text, rtf...) for you to use on your app of choice. It's certainly better to buy DRM-free books directly if you can find them, but the above solution works quite well.
