"I would argue that my experience of the book is actually enhanced by listening to it. It may take a bit longer than my usual speed reading to get to the end, but many of the subtle nuances that I would normally gloss over in my haste to get to the next page I actually pick up while listening to an audio book."
Actually, I found that I miss a lot of things when listening to an audio book compared to when I read a (real) book. I guess if you're into speed-reading and skipping half the words, you would pick up more of the story if someone else is reading every word to you!
Another disadvantage of audio books is that, in a world where "meh", "moar" and "nao" appear to be all too common, the consumer does not learn proper spelling from the experience.
Somehow, though, I don't think the author of the article is representative of the average reader.
