Whether or not you own an e-reader, you've probably heard of one. These digital alternatives to printed books are taking the tech-savvy world by storm, led in part by these e-reader creations.

From novel Kindle covers that look just like well-worn books to super-sized e-readers that mimic the size of a newspaper, these creations embody the future of literacy.

Implications - Businesses can benefit from creating e-versions of their books. The popularity of e-readers has risen in the past year and is continuing to increase with newer developments of the iPad and the PlayBook. By offering their books as an e-version, publishers can potentially earn more money and conserve costs that are created from printing.
