Yeah. I grew up in the days of serial ports and parallel ports, and USB in general is so much better for most purposes. (I recall plugging my first mouse into the serial port...but wait! Where will my Hayes Smartmodem modem plug into then? Also, don't plug and unplug things from the serial port while the computer is running.)

And USB-C is even better. My tablet needs a charge? Well my laptop charger is right here... My phone is low and needs a quick charge? Well my USB-C tablet charger will give it a decent boost very quickly. No worries about getting it plugged in the wrong way, either.

I have a docking station for my work laptop, so when I had to replace my personal laptop, a laptop that supported USB-C power delivery was mandatory. I don't use it with the docking station very often, but knowing I can without an issue is great. My wife also has a Macbook that works on the docking station, too, in case she ever wants to use my dual monitor setup. All three laptops, from three different brands, are just plug in and go.

I can't imagine how you think it's incredibly simple. These things are hell to explain to pretty much any normal person who needs to know why there's no picture on the monitor or why their laptop/phone is not charging, or why the keyboard isn't working in BIOS (no USB 3 support so you gotta switch to a USB 2 port). Add to that the combinatorial complexity of different cables and hubs supporting different things, and no tools for troubleshooting what feature is missing (and where in the chain) or what is suboptimal.

Worse, sometimes it's my boss who thinks they can cheap out and get a USBC dock instead of a proper dock, forcing me to run at non-native lower resolutions or unable to use a second screen.
