Great news for us musicians on the PC side of things:
Intel finally had enough of Apple's shenanigans with their proprietary Thunderbolt connector that produced little revenue for the microprocessor giant. The introduction of Thunderbolt 3 which is uses as bypass via the new USB-C connector, pretty much cuts Apple out of the loop (for those that didn't know Intel owned the patents on the bus technology of Thunderbolt formerly called lightpeak, Apple only owned the connector piece). This new connector is already showing up on hundreds of new PC's just being introduced in the market, and within the next 3 years it will be as ubiquitous as all the other USB standards are.
One port to rule them all!
USB-C will allow you to connect Thunderbolt 1 and 2 devices via an adapter, and many of the interface manufacturers are already working on Windows drivers for their Thunderbolt products.
Future proofing as this new USB port will be used as a charge port, it will come on smartphones, tablets, and PC's, and supports USB, Thunderbolt 1/2, PCI Express and Display Port standards.
These ports are already showing up on new PC's, across multiple manufacturers.
This is a win for consumers and giving people a choice and will give us musicians on the PC side of things access to all kinds of new interfaces that were previously Apple only. Focusrite's Clarett line of Thunderbolt interfaces is already going to release Windows Beta drivers.
