An e-book device is a device specifically designed for reading material. It can hold a large amount of reading material and minimize weight, especially if you like reading more than one book at a time.
They are very useful when you have a lot of white papers, reports and other PDF type documents to read and just don’t get time in your office. It allows you to get away from your computer to a more conducive reading environment to concentrate and absorb the information.
The e-readers have easy search capabilities especially when looking for that one phrase, quote or topic. They also have the ability to take electronic notes or highlight text. The Amazon Kindle and the Sony Reader are good, basic e-readers and do well in bright sunlight. The Apple iPad can also be an e-reader with a lot more computer features and functionality.
