I know everyone has a different step but I would welcome two usb C ports over a regular port just because the I can get a powered usb c dock that is connected to all my peripherals. That way all I have to plug in when I get in to work is one cable.

This was the #1 use case for Type C development BTW. I have friends who were working on silicon this for over a decade.

I anticipate that 2019 will be the year when we'll get monitors that are the "dock", so in practice most users will use at most a single port.

I already do this, and it's wonderful. I had to get a monitor that was way too big though to find one that had all the ports I want and which could supply enough power back to the laptop, but I assume smaller monitors are getting it by now too. Still though, it's well worth it if you need a new monitor to wait for one that has all your preferred specs and also does USB-C, I don't think I could go back.

I plug in my laptop and the monitor comes on, my keyboard and mouse start working over USB, my speakers start working because I turned the builtin soundbar off and enabled the in USB-C/3.55mm DAC that's also built into some Dell monitors, and even my printer and a synthesizer that I use as a practice (piano-)keyboard are are ready to go.

They are already pretty widespread, but expensive for now. I have to regularly use at work a Dell XPS 13, a macbook and a Lenogo Yoga. The monitor I use is an HP Z27 with a built in dock, where I have a keyboard and mouse connected. Whenever I have to switch a laptop, I just unplug the usb-c cable of the monitor from the laptop I am using and plug it to the new one. It takes a couple of seconds and I have my full setup usable again. The best thing is that it also provides power to the laptops, so I do not have to plug them.

In the past, when I was connecting a laptop to a monitor I had two options:

1) Use a proprietary dock. This is as convenient as the usb-c cable, but you can use it with a single brand of devices. Also, in the case of the usb-c cable you are free to move the laptop around the desk. Not so easy with a dock.

2) Plug the monitor and the peripherals directly the ports of the laptop. When you have to switch laptops frequently, it feels like this process is taking ages. It also looks ugly to have an octopus laptop on the desk.

Having said that the dedicated usb-c docks are notoriously problematic. I have tried a lot to find a single one with more than 3 star reviews, but it seems impossible. At least, I have not heard complains about the built-in docks inside monitors. In this case though, you have to make some sacrifices in the number and variety of ports. For example, in my case, I do not have ethernet.

There are already screens like that, and I like the idea in principle.

I'm more hesitant in practice because the USB3 hub in my current Dell display didn't get along with my computer and would cause blue screens when used. Easy to avoid, I just don't have the USB hub plugged in.

As things get more and more integrated, a problem anywhere in the system means the whole thing doesn't work and you can't avoid the busted parts.

That's a general issue: laptops are pretty integrated and even in your tower it's pretty hard to patch the mobo (and let's not get into the issue of upgrading your L1 cache.

I started computing on a machine (PDP-6) on which you could add instructions with a wire wrap pencil. That's clearly impossible today, but with modern manufacturing, increased integration typically means increased overall reliability.

All true, but the benefits of integrating those things are more obvious to me than "you don't have a separate USB and power cable."

On the plus side, issues like mine ought to become less common with an integrated device, since it would become impossible for Dell to not test their USB hub when they plug in the display cable.

And I suppose I've considered a thunderbolt hub for the convenience and decided against it just because of what they cost. If that sort of integration were "free" with displays, yeah I'd probably take it.

I have a Dell monitor which does video, audio, power, and a couple of USB ports over USB-C. It’s easily the best setup I’ve ever had just for the convineance in being able to plug in one cable and immediately have everything I need working.
Such monitors are pretty common now, at the higher end of the market, but most of them cannot charge larger laptops like 15-inchers that need more than 80 watts.
This is my primary concern with the whole "charge your laptop through peripherals" trend promoting usb-c. My laptop ships with a ~200W PSU, so anything that wants to reasonably charge my it needs that amount in excess power. I just don't see it being economical to stuff that king of power into everything. Not to mention I can't even find a 200W usb-c wall charger...

I wouldn’t recommend buying one if you saw one — the power delivery spec only goes up to 100 W!

Some of those monitors already exist such as the Dell 38" (depending on your definition of dock; it doesn't have Ethernet).
I've had this setup for a couple of years. Back when I started out on it, with a Dell XPS 15 (9550) and Dell docks, reliability was pretty iffy; unusable for their TB dock and kind of flaky for their USB-C dock. The latter is the only one that has proven in the long run to be a decent implementation; when I switched to a Thinkpad (P52s) a year ago the USB-C dock ended up working just fine, and the TB dock was recalled and replaced and now is just flaky.

I'd either go with a hardware combination that you or a trusted reviewer has tested, or wait another year or so for the bugs to get worked out.

EDIT: Or just avoid Dell, they seem to be behind the curve on figuring out Thunderbolt 3.

Even well reviewed devices aren't guaranteed to work. At work I had a TB3 dock from Belkin, that was one of the top sellers on Amazon. Everything worked on the MBP, but when I tried connecting my ThinkPad (T470s) all the peripherals and displays worked, however it wouldn't deliver any power. On the other hand the cheap Chinese TB3 dock (UGREEN branded) I have at home works fine with the ThinkPad.
Same here. My work laptop is a HP Zbook workstation. My favorite thing is my USB C doc. 4 USB ports, 2 display ports, Ethernet, USB c port, power, and a VGA port.
