kijin,

I used "The Idiot" because that was the book that I was reading at the time of this writing. Using Calibre doesn't directly combat DRM, but the time you spend using it as a broker for consumption is time you are not spending in the B&N store buying books in a restricted format.

Though it may seem silly to read public domain books when there may be something new that you want to consume, if you can forfeit that experience of a new book, it is a great form of protest.
