An e-reader, sometimes called an e-book device or e-book reader, is a mobile electronic device that is designed primarily for the purpose of reading digital e-books and periodicals.
An e-reader is similar in form to a tablet computer. A tablet computer typically has a faster screen capable of higher refresh rates which makes them more suitable for interaction. Tablet computers also are much more versatile, allowing one to consume multiple types of content, as well as create it. The main advantages of e-book readers are better readability of their screens especially in bright sunlight and longer battery life. This is achieved by using electronic paper technology to display content to readers.
Any device that can display text on a screen can act as an e-reader, but without the advantages of the e-paper technology.
Specialized devices have the advantage of doing one thing well. Specifically, they tend to have the right screen size, battery lifespan, lighting and weight. A disadvantage of such devices is that they are often expensive when compared to multi-purpose devices such as laptops and PDAs.
In 2010, competition sent the price for the most popular electronic reading devices below US $200. (from New York Times article)
