Exactly right. And I made the jump and bought a USB-C monitor which plugs right into the MBP and charges and connects video in the same connector (which is awesome). Then I bought the USB C to Lightning cable, which fast charges my iPhone. I wish Apple had gone with USB C for the iPhone instead of Lightning, but I think they are too deep in with Lightning at this point.

I have the HDMI/old-USB to USB C dongle, but I hardly ever use it these days.

I'd gladly support an all USB C future.
