With my Macbook Air, I needed a Mini-DisplayPort to HDMI adapter. With my Retina Macbook Pro I also picked up a Nexus 5X, so I needed a USB-C to USB-A adapter. With my wife's Touchbar Macbook Pro I need a USB-C to USB-A adapter and a USB-C to HDMI adapter. Finally, with the X1C, I need none of these. I have no doubt that USB-C / Thunderbolt 3 are the future, but as a transition laptop, I couldn't be happier.
