I wouldn't. There is more value in a 'real book'
than in a drm-locked e-book (in my personal opinion). I would pay close to a physical book cost if the SELLER sold it pre-de-DRMED.
I get more of a sense of ownership with the physical book because I get total jurisdiction over what happens to it released into my hands.
I often see hardcover books that are cheaper than some e-books. People can justify the costs all they want with fancy wording, but I never will be duped.
