With the progress of times, e-books are gradually entering our lives. I believe that after a few years, they will be widely popularized, replacing a lot of paper books, magazines, and newspapers如今. However, the e-books currently available on the market seem somewhat clumsy. This dual-screen, internet-enabled e-book is by far the thinnest and lightest e-book I've ever seen. Of course, besides being thin and light, it has many unique features. In addition to the regular screen used for reading books, it also has an extra smaller screen. Through this additional small screen, you can surf the web, view images and video files. It's also a touch-screen keyboard. If this kind of e-book really hits the market at a reasonable price, I believe there will be a lot of people interested in purchasing it.
