The convenience of e-books had already surpassed physical books. Was there still a need to buy e-books? This was a very subjective question because everyone's needs and preferences for e-books and physical books were different. The advantage of e-books was that they could be read anytime, anywhere, without the need to carry a physical book, and would not be limited by weight and space. E-books can also be purchased and downloaded at any time and place through the Internet. In addition, e-books could also be interacted with and added content through some applications. On the other hand, physical books could provide higher value and make it easier to store. A physical book could allow readers to feel the author's imagination and creativity, and at the same time, it could allow readers to better understand the story and characters. In addition, physical books could also allow readers to better preserve and organize books. If one paid more attention to the convenience and convenience of e-books, it might be more appropriate to buy e-books. However, if you prefer the value and preservation of physical books, then buying physical books may be even more necessary.
