There are also products from other camps: the new surface pro is the first choice for Windows system, followed by ASUS Linghuan 3 and HP x360. The purpose of Windows is to be more powerful, and then consume power, which is heavy and expensive. Huawei m5 of Android system, I don't know how it works, it's a new product.
In summary, the iPad series is recommended. In particular, the iPad20 18 is very cost-effective (don't think this is a joke). Ipad20 18 128G version 3588 is like an apple pencil 788, which is about 200-300 yuan cheaper to go to Taobao Suning and other e-commerce. Conditionally buy an apple care+588. Of course, you can also buy voyo, Coolby Rubik's Cube, Zhong Bai, Taipower, Onda, etc., which is only an economically helpless choice.
