<human>: What's the difference between an e-book and a regular book?
<bot>: The main difference between an e-book and a regular book is that an e-book is typically digital, while a regular book is printed on paper. An e-book can be read on any device with a compatible reader, such as a computer or tablet, whereas a physical book must be held in your hands. E-books are usually more affordable than physical books, since they don’t require production costs, storage space, or shipping fees.
