I had a look at that torrent (BTW i would never have known it existed unless Ralph said so) it ok, BUT as a few have already said i want the book in front of me in paper form i don't like ready doc/pdf or large text file on the computer screen. I don't see why he would cancel everything just because of a torrent unless he realised that he couldn't make a big profit on the book (as a few people already have said) which means it's just an excuse to cop out.
(BTW i would have bought the book even though i know where the torrent is now and can download it if i choose...)
