A wireless reading device is a small, portable, electronic device which allows the user to download and read books, magazines, and newspapers. It may also be referred to as an eBook reader. A computer is not required when using a wireless reading device; the device is capable of connecting to the Internet and instantly downloading any print media that is available. These reading devices also have special screens that, instead of looking like computer screens, use "electronic ink" that mimics the look of a page in a book. This is intended to prevent eye strain and virtually eliminate glare if reading in a bright or sunny location.

Most wireless reading devices are capable of storing hundreds to more than a thousand books, which means that you can take your entire library with you wherever you go. Books not loaded onto the device can be stored online or on your computer's hard drive for later use; they are not lost or deleted. The devices are designed to be thin and light, to fit easily into a bag or purse, and to be easy to hold. Commonly, specific buttons allow you to turn the page or increase the font size, and the device will also feature a small keypad or touch screen for typing. Some have the capability to read out loud to you, or to play an audiobook.

Though not all books, magazines, or newspapers are available to be downloaded to a wireless reading device, there are already hundreds of thousands of options, with more being added every day. Many companies allow subscribers the opportunity to cancel their print subscription, and instead automatically receive the latest issue right to their wireless reading device daily, weekly, or monthly. In addition, books and other media purchased for a wireless reading device are generally substantially cheaper than their printed versions. These reading devices also commonly allow the user to view blogs or personal documents as well.

Wireless reading devices may include other beneficial features such as a basic web browser, built-in dictionary, an annotation or bookmark feature, highlighting, and a search feature to look for a specific section within a book. One notable downside is that these devices run on a battery, and will need to be charged periodically. Though most have a long battery life of a few days or weeks, it could be an annoyance if you are traveling with the reader and the battery runs out.

Most wireless reading devices range in price from $200 US Dollars (USD) to approximately $400 USD, though this changes constantly. They generally come with a one- or two-year warranty against defects. Though it is an expensive purchase up front, over time it will likely save money and prevent waste, considering that wireless reading devices are also better for the environment than the constant purchase of newspapers, magazines, and books.
