To listen or not to listen?

Reading according to Websters Dictionary is an  activity of interpreting music, a situation, or something said or written.   But it also means to be able to read a written or printed text.  Today one can read in a variety of formats; the traditional format can be read on the computer, on one's kindle, or on a traditionally bounded set of printed words.  But also reading is now being defined as listening to books; the reader can listen to complete books via audio c.d.s or via a MP3 file, on their computer.

But is listening to an audio book reading?  Does listening to a book constitute the same experience as reading one?  Will the reader's reaction to the book be influenced by the listening experience?  Some authors have published and read their own works on an Audio format.  Neil Gammon read his Graveyard Book and recorded it onto C.D..  I ponder if my liking Fahrenheit 451 was due me listening to it, and not reading it.  Bradbury is a really good oral story teller, but is his writing good?  Hmm we ponder!
