There are a lot of factors to consider when deciding whether or not to buy an eBook reader. First, consider how often you would use it. If you only plan on using it occasionally, then it may not be worth the cost. Additionally, consider what type of books you prefer to read. If you like to read physical books, then an eBook reader may not be the best option for you. Finally, think about the cost of the device and the cost of the eBooks.
