It looks like USB Type-C will be one of the big stories of CES 2016. The USB Type-C connector found on the 12" MacBook makes it possible to transfer data and display content on a monitor, and at the same time provide power to the MacBook as well.
Having a USB Type-C equipped monitor basically allows said monitor to function as an all-encompassing docking station for the 12" MacBook. With a single cable, you can provide data transfer, monitor connectivity, and power.
Today, Acer has announced a new line of monitors sporting the H7 series moniker. These monitors are among the first displays to sport USB Type-C connectivity, and when you think about the implications, it's a very big deal for MacBook owners.
