What notebook is worth to buy in America?

It's easy to check the notebook parameters.

Computer stores in the United States have special parameter testing, which is very professional and more than N better than domestic amateurs.

In terms of quality, please rest assured. If there is something wrong, you can complain, and consumers there can get more than twice the compensation. It won't be as disgusting as it is in China.

You can look at DELL or GATEWAY or MAC

The best portable performance plus ultra-thin is the MAC BOOK (as for the software you mentioned, you can talk to the shop assistant and they will help you. After you come back, you can reinstall the domestic GHOST version of the Apple system.)

Either choose GATEWAY, which is also a good brand in the United States and has a good portability.
