Macbook Neo的USB接口

Daring Fireball今天的文章中介绍了一个小知识点： 

On the one hand, this stinks. It just does. The two ports look exactly the same — and neither is labeled in any way — but they’re different. But on the other hand, the Neo is the first product with an A-series chip that Apple has ever made that supports two USB ports. It was, I am reliably informed by Apple product marketing folks, a significant engineering achievement to get a second USB port at all on the MacBook Neo while basing it on the A18 Pro SoC. And while the ports aren’t labeled, if you plug an external display into the “wrong” port, you’ll get an on-screen notification suggesting you plug it into the other port. That this second USB-C port is USB 2.0 is not great, but it is fine.

一方面，这确实很糟糕。两个接口看起来完全一样——而且都没有任何标识——但它们其实并不相同。但另一方面，Neo是苹果首款搭载A系列芯片且支持两个USB接口的产品。据苹果产品营销人员可靠消息，在基于A18 Pro芯片的MacBook Neo上能再增加一个USB接口，本身就是一项重大的工程成就。虽然这些接口没有标识，但如果你将外接显示器插入“错误”的接口，屏幕上会弹出通知，建议你插入另一个接口。第二个USB-C接口只是USB 2.0规格，这虽不算理想，但也还过得去。

Perhaps the closest Apple had ever come to an A-series-chip product with two ports was the original iPad from 2010, which in late prototypes had two 30-pin connectors — one on the long side and another on the short side — so that you could orient it either way in the original iPad keyboard dock. 

或许苹果公司推出的配备两个接口的A系列芯片产品中，最接近的要数2010年的初代iPad了。在后期的原型机中，这款iPad有两个30针接口——一个在长边，另一个在短边——这样你就可以将它以任意方向放入初代iPad键盘底座中。
