My own survey of digital reading

We recently heard an announcement that Raising the Ruins was now available as a Kindle book on Amazon. I am very happy about that as I am more of a ebook reader than hard copy, mainly because it's so accessible and I find annotating the text easier. Anyway...in the announcement it mentioned that Amazon said sales of Kindle books outstrips hard copy books.

While sitting here in the departure area, I decided to take me own visual survey.  I saw first hand evidence of the popularity of digital content. As I came down the escalator to the waiting area, I saw two people below me, one with an iPad and the other a Kindle. In the seating area  my count was 11 people with digital reading devices (Kindle, iPad or Nook) and 3 people with books. Interesting.
