What's out there is called either electronic paper or electronic ink (or
abbreviated e-paper or e-ink). Two companies are working on it, one a
Xerox spinoff, the other an MIT spinoff. The basic idea is that you have
a sheet of material that is roughly paper-like in terms of thickness that
contains small pixel-like bits of a substance that can turn white or black
when hit by an electric charge. So you can plug in the e-paper (or a book
of it) to a data and power source and it will reformat its contents to
display the new information...as well as in whatever font(s) or size(s)
you want. The real beauty is that once set, it doesn't need a continuous
power supply to maintain the content, so it is a book you can take to the
beach, read in the bathroom, etc. without having to plug it in or worry
about battery life when reading it.

There are examples out in the real world, mostly signs in department stores
and the like. They're still working on getting the pixel size down to
where a book size would have reasonable print quality. Personally, I really
like this approach as it combines the storage strengths of computers with
the display strengths of books. While there are certainly "real" books I'd
want to keep, I wouldn't at all mind shrinking a large part of my library
down to a shelf of DVDs.
