USB-C is cool but there's no reason they couldn't make a MagSafe USB-C port.
My only complaint about the usb-c is that they're on the same side. I've gotten used to flipping back and forth on my mbp for plugging it in. (different setup at home and work)

It worked, but it seemed to take 2x - 3x longer to charge using that cable than a normal USB C cable.
I never tried it on anything else though, so I'm not sure if I had a bad cable or not. It worked, it just charged very slowly compared to normal cables.
