In a review of John Keegan's The Face of Battle, John Walker mentions that the edition of the book he read was the one for Kindle eBook:

I read the Kindle edition using the iPhone Kindle application. It appears to have been created by OCR scanning a printed copy of the book and passing it through a spelling checker, but with no further editing. Unsurprisingly, the errors one is accustomed to in scanned documents abound. The word “modern”, for example, appears more than dozen times as “modem”. Now I suppose cybercommand does engage in “modem warfare”, but this is not what the author means to say. The Kindle edition costs only a dollar less than the paperback print edition, and such slapdash production values are unworthy of a publisher with the reputation of Penguin.

Yet another reason I don't want to rent, er, read, eBooks using a Kindle, iPad, or whatever: when something analog gets digitized, something gets lost along the way.
