Plus power. That means two cables! That's literally double the number of things I should need to plug in.

I hate to admit that this actually bothers me. It's true of all laptops, though.

Given that Thunderbolt 3 can supply 100 Watts out - you would think there would be an equivalent trick one could do to bring power in

The new Lenovos have a "one dock" plug that does USB, video, and power on one plug. It's lovely.

Yet another reason for my next laptop to be a Lenovo...

Last time I saw a USB dock with video the video performance was really poor, max 30hz at 720p etc... Do you have any experience of how these work?

I'm guessing the dock is Thunderbolt, since Intel CPUs support it directly, and it does video, USB, and power.

Wait, so USB 3 still doesn't solve the problem of "Host needs to draw power from the connection"? That the connection has to be in client/charging mode or hosting-periphs/supplying-power mode?

That's always been a massive disapointment in USB - the fact that you can't host and draw power through the same port at the same time. Big part of the reason you don't see many docks for non-iOS devices.

For MacBooks there's these things: http://hengedocks.com

I had one for an older laptop. Worked fine, but I didn't use it much just because I wasn't at my desk at home very much.

The cables really don't sound like that big of a deal.

I'd much rather use a wired keyboard and mouse anyway. Every wireless one of either that I've tried has had lag and connectivity issues.
