PLaying devil's advocate...
Pbooks have their faults, too - usually uncaught typos, the occasionaly continuity error; but also books bound in the wrong order, pages creased and uncut; and every now and again some real howlers on the back - my two favourites were a book on the 60s classed as Fiction, and the back blurb starting with what the copywriter called the famous first sentence or somesuch - and got it wrong.
The ebook I've just finished had the odd hyphenation problem - but it was free so I'm not complaining too much!
