This tweet certainly caught my eye, as I am a female and proud owner of a Kindle.  The article on Mashable’s website has two graphs that show the increasing trend of women with eReaders and increasing trend of people over 55 years of age using eReaders.  The article does not comment on the use of eReaders in higher education, but at least these data show that instructors should not expect a gender gap on who embraces an eReader.
