Yes, it’s convenient to plug or unplug just one USB-C cable into the laptop. But … it was even more convenient to just set the laptop on the docking station and push gently to latch it in, then push the eject button to free it. All gross movements, not fine movements requiring good eye-hand coordination. And the docking station never slid off the back of the desk.
Also … USB-C is as janky as any docking station: From time to time, it just doesn’t connect to the mouse, or the ethernet, or the scanner, all of which are connected through the USB hub on the back of the big Dell monitor. I mean, it’s cool to hide cables in the monitor arm. (The keyboard and mouse use a tiny wireless receiver.) Before the monitor, I tried a bunch of USB-C docks, all of which simply didn’t work at all.
But I’ll stop complaining. Yeah, it is an improvement.
