E-readers are portable electronic devices designed specifically for reading digital books, magazines, and other written content. They use a special screen technology called E Ink, which mimics the appearance of printed paper, making it easy on the eyes. E-readers can store thousands of books, allowing users to carry their entire library wherever they go. Popular models include the Amazon Kindle and Kobo. One of the main advantages of e-readers is their adjustable font size and built-in lighting, which enhance the reading experience. Many e-readers also offer features like dictionary access, highlighting, and note-taking, making them versatile tools for both casual readers and students.
