At a coffee shop or similar establishment that offers free wireless Internet, a person who is oblivious to everyone and everything except the screen in front of them is called a laptop zombie.

在咖啡馆等免费提供无线网的场所，那些对一切人事不闻不问，只对着自己的电脑屏的人就叫做“笔记本僵尸”。

Example：

There are many laptop zombies lurking in Starbucks.

星巴克里潜伏着很多“笔记本僵尸”。
