This is obviously far more advanced, but I still think its a shame that the old style thinkpad dock didn't catch on more. For those who arent aware, the docks on old thinkpads used to double as a stand (and a lock too actually), originally connecting via a custom connector at the bottom of the laptop and then over dual usb-c slots.

I saw plenty in corporate environments but I think people mostly wanted to use a larger and better screen than what was available on a laptop at the time.

What I never saw in the wild but which was neat was the Powerbook Duo dock that pulled in the laptop like a front loading VCR tape, peak Sculley-period pointless complexity. It totally enclosed the laptop in a closed configuration, the idea being that you would put a monitor on top of the dock.
