Digitimes has been chatting to its “industry sources” and discovered that they are not so keen on USB-Type-C as expected.

It found that notebook vendors were less enthusiastic about the interface with only a few of them planning to adopt one USB Type-C port for their new products for the second half of the year. This means that we are unlikely to see much The USB Type-C interface is unlikely to become a mainstream technology in the notebook market until 2017.

USB Type-C interface has two issues that are sticking the brakes on it being mainstream in the notebook market. The interface features electric current that is larger than one of the previous-generation interfaces, and could lead to interference and heat dissipation problems when adopting too many at once.

USB Type-C also has high-speed transmission, but needs an amplifier chip, a receiver chip and a special-spec transmission wire, which jacks up the product costs.

Only Apple has signed up for the USB Type-C interface for its MacBook Air. Asustek and HP are upgrading one of their notebooks' regular USB port to the Type-C. Lenovo, Acer and Dell are still thinking about it.
