Fiske's Reading Machine was a pre-silicon Kindle

E-readers have become one of the most pervasive pieces of tech for many reasons. They survive alongside tablets because they're accessible -- Amazon's entry-level Kindle is just $80 -- and don't require daily charging. E-ink displays don't strain your eyes nearly as much as backlit screens, nor do they keep you up at night. Above all else, though, they can hold the entire works of Shakespeare countless times over while being thinner and lighter than any paperback. But this idea of portability, of condensing the written word into a format only a device can understand, is older than The Great Gatsby.
