I don't understand the port fetish. I admit my mac use case doesn't involve plugging much of anything into my machine, but Type C is pretty ubiquitous by now.
It hit me -- hey, solve this latency issue by using wired ethernet. Then I remembered, HEY, I already HAVE an adapter. Chained my apple-multi-port-adapter to my apple usb-to-ethernet adapter. Wait, why are things worse than WiFi? Oh, right, USB type A, probably USB2.0 or whatever. Limited to 93Mbps.
Go to apple store online, order Thunderbolt to Ethernet adapter. I've made the mistake of buying a USB-C dock instead of a Thunderbolt dock, won't make that mistake again!
It arrives, it's Thunderbolt 2 so it can't plug into my machine.
Order another one, this time USB-C.
