Nobody's going to argue that USB-C is a good idea. The entire problem is the lack of available devices. Period! To sell a computer that needs adapters to be put into use right now is idiotic. To adapt to this standard every manufacturer needs to re-design boards as well as completely change production. This might have been a good idea two or three years from now, but now? No. It's poorly thought out.
I seem to remember people praising the greatness of the the Thunderbolt a few years ago. Where are all the Thunderbolt drive enclosures? Where are all the Thunderbolt drives? It didn't take off.
It's tough titty. That's the way Apple does things. They don't listen to marketers. That's why there stuff is better. If you don't want usb-c then go elsewhere. Nobody cares.
