If it was my mother who is 87 and she bought a device that wouldn't work for her she would just return it and get one that would (another kindle keyboard if they still sell them
)
I am thinking most that are happy with what they have will simply buy from the same vender.
What surprises me are the people who have no desire to upgrade. Of course they are probably smarter and richer than I am as I have several ereaders and only need one.
