What are some key features and benefits of USB-C?

The ability to use a single cable for data transfers, to deliver video to a display, and power delivery are the key features of USB 3.1 Type-C. This allows it to be used to daisy chain multiple devices together, in much the same way as Intel's Thunderbolt interface is used in Apple products. However, it delivers this functionality at about a quarter of the cost of Thunderbolt, making it a much more suitable solution for consumer use.
