I became enamored of Kindle.  I downloaded about three different bibles.  KJ rules!  Most written material over 50 years old is out of copyright so you can find downloadable digital versions of all your favorite older (“older” is pretty relative!) material.  Even if the format is not friendly there is free software to convert it.  Between this and “free” Kindle publications I was spending about three hours a day downloading, reading and organizing.  With my running and yoga I found I was not doing much else.
