E-Readers 

The 'Amazon Kindle', the best selling e-reader today.

E-Reader manufacturers make their money from selling the actual e-reader devices and from selling the books, but recently there has been speculation around giving away the e-readers for free or at a very low price to encourage people to buy the books because they believe that the book market is bigger than the e-reader device market; for example China's biggest selling e-reader the Hanvon N510 has had to cut its price by 40% to compete with other, cheaper e-readers and of course the iPad. Since the E-reader market is relatively recent company's are working hard to try and dominate the market like apple did with the iPod and with iTunes. Maybe in a few years if an effective efficient and affordable e-reader comes and dominates the market than maybe the hard copy books will slowly disappear like the cassette did when the CD first came.
