Yeah, tell me, did the guy choose one with a 4K display and a Thunderbolt port? Yes. Yeah?

告诉我，那个店员选了4K显示屏，还带有雷电接口的吗，是的，是吗？

Since the Air can now charge over MagSafe, you effectively get an extra port because you don't have to use one of the two Thunderbolt ports for charging anymore.

由于 Air 现在可以通过 MagSafe 充电，您实际上获得了一个额外的端口，因为您不必再​​使用两个 Thunderbolt 端口之一进行充电。
