I think that older and elderly people have an increased proclivity towards reading; compared to those under 30. Of course I really don't have any hard evidence beyond time spent working at B&N through college, and knowing friends and family. *chuckle* Then again, somehow I can't see my great aunt using a Kindle; she's still scared of computers and I'm amazed that we got her to carry around a cell phone.
This woman might have small point though. I often wonder exactly who Sony, Amazon, and the other ereader peddlers, have decided to market their devices towards.
