Cage Chao and Joseph Tsai, reporting for the notoriously unreliable DigiTimes on the industry’s slow uptake of USB-C:
Currently, Apple has decided to adopt the USB Type-C interface for
its MacBook Air, while Asustek Computer and Hewlett-Packard (HP)
are upgrading one of their notebooks’ regular USB port to the
Type-C. Lenovo, Acer and Dell are still evaluating the option.
It is possible that Apple has a significant update to the MacBook Air in the works. But my hunch remains that they do not. If there’s any truth to the above, I’m guessing the above is actually the new MacBook Pro.
