I have the same mac pictured above, and also a windows laptop with many ports.
The mac I plug into my work center via a single usb-c connection which charges it, connects it to my external monitor, and connects it to all of my USB equipment (about 6 items ranging from m&k to music equipment). Having only the one wire is huge in terms of making it easier to break down the machine from its setup and pack it up for the road.
The pc is connected separately to power as it can’t be powered through the usb-c, and to the monitor separately for some esoteric reason. So then I need a third cable to connect it to my equipment.
So in my case the less-is-more approach is actually preferable
that all being said
I’m sure other windows laptops can be configured with a one-wire solution just fine. And I don’t mean to pretend the 2x usb-c config was a popular choice or anything. Only on like two models or something had it. The newer macbooks brought back sd card slots and hdmi and everything by popular demand.
I looked into it and you can still run everything off of just one usb-c on those ones, so at the end of the day more options is just better for more people
Thank you for proving me correct!
