Interesting survey, although I didn't find the questions to be very indicative of the people who are over 50 and their use of ebooks.

Just late last year I gifted the m-i-l with a Sony PRS 600. Took a few minutes to show her how to use it and she's been in love ever since. Same thing with her daughter (age 49). Several of their friends have since gotten ebook readers after being shown how easy it is to use them. His survey really didn't have any questions that could show this kind of information :(
