Sorry for prolonging the OT. There's some contextual irony here: I downloaded a torrent of a cam version to tide my wife over when she was too sick to go to the theatre for the 5th time. Big grateful response.
I then downloaded a dvdrip two weeks before her pre-ordered disc set arrived, which was met with a mild reception. "Meh, my disc will be here soon, I can wait."
She would have asked me to rip her DVD to play on her Touch, so it's good to know I should hold onto the copy I have.
I lost interest in the book, and wasn't that impressed with the movie. BUT I did enjoy The Host, by the same author.
