Writing and reading on an iPad was possible. The iPad did have a built-in keyboard. I recommend the iPad Pro, which has excellent performance and good battery life, and also supports the Apple Pen and Smart Keyboard. With this iPad Pro, you can easily write and read books, and the keyboard feels very comfortable. In addition, the iPad Pro also supports a variety of software including iMovie, Adobe Premiere Pro, etc. to help you better edit video and audio. Of course, if the budget is limited, you can also use other brands of electronic products such as the Huawei Matepad Pro, Xiaomi Pro, etc. They also support the Apple Pen and Smart Keyboard. The performance and user experience are also very good.
