I can wholly appreciate the frustration felt by the author who is being pirated, as this is a war which will likely never be won.  However, I do believe that a previous commenter was making a valid point regarding the marketing of eBooks.  

Let me first agree that creative works absolutely have value, and are a genuine product.  I am simply offering this point for consideration in the discussion.  I am not advocating piracy, regardless of anyone's moral or legal compass.  

Now, let's consider some of the marketing models taking shape in the ebook realm.  Publishers are often pricing the ebook versions of the work above the print editions, significantly more in some cases. This is despite that fact that there are absolutely no production nor delivery costs associated with the digital versions.  How do you think this pricing model impacts the <I>casual downloader</I>?  

Sites like the one detailed in the post above are, believe it or not, one of the more cumbersome ways to download material.  There are whole sections of the internet, that predate the WWW, where one can find virtually anything and have a copy of it within 5 minutes or less, with no uploading peer necessary.  Imagine that, 2-3 YEARS worth of anything ever uploaded, just sitting out there for anyone to peruse and download at their leisure.  I could have downloaded and been reading David's entire library of work in a fraction of the time it took to compose this post!

So when Johnny New-e-reader goes out to grab his favorite new book, and finds a $15-17 price tag, while the hardcover edition is selling for $12, there is going to be a moment of decision where the casual consumer decides to become a pirate, or <i>click here to buy</I>.  I believe that many justify piracy because they feel like they are being ripped off if they buy the product - and charging more for electronic versions certainly does little to refute the claim.  

As stated in a previous comment, the content producers that figure out how to make legitimate (paid) consumption more convenient - and that includes pain in the wallet - than downloading a  pirate copy will win the war.  The success of Netflix or RedBox, vs the demise of Blockbuster further illustrates this point.
