Exhibit A:

Why is that thing not built into the new generation of Macbooks? If you need adapters anyway, why not also adapt to USB C from Magsafe? Provide four Magsafe Thunderbolt 3 ports, and provide adapters to USB C, USB A and Thunderbolt 2. You have elegance, you keep the brilliant Magsafe thing, on all ports, and you can spin the adapters by saying that you made all ports detachable and universal, compatible with all existing port standards. I would actually find this more plausible than the USB C.
