As much as people complain about USB-C, I absolutely love it. I have a 2018 MacBook Pro, and I use the Caldigit TS3 hub (referenced in the article) as my docking station at work. I plug a single cable in, and I immediately have 2 x 27" 4k monitors, power, USB peripherals, headphones, Ethernet, and much more if I need it.

I travel with a single dongle that cost $15: SD card, HDMI, 2xUSB 2.

I have not had to buy any extra cables, besides what came with the computer.

Not only that, but the USB-C plug itself is the worst-designed plug I have seen in a decade. It's flimsy sheet metal on the plug side with a nice big cantilever, and flimsy sheet metal soldered to a PCB on the other. Perfect recipe for broken ports and cables. I break about a cable a week and break a device every now and then. Mostly doing very normal things like charging a phone in my pocket while hiking. USB-C seem…

> I break about a cable a week and break a device every now and then You're doing it wrong then. I have about 5 USB-C cables and have never broke one in 3 years... Kinds of cables I have broken over my IT life: - A few Apple charger cables (on the Mac connecting end) - A few headphone cables

I disagree with the notion that just because they break that I'm "doing it wrong". Please listen to the customer. Rather, I'd say that they're just not rugged enough for my (consumer) standard of use, which needs to be more rugged than office use. I have legitimate needs to engage in sports while devices are plugged in and accessible. Other consumers get stuff bitten by children and pets, stepped on, tangled, and caught in things. That's consumer life. It should be accepted as a valid design problem to make a product rugged enough to tolerate that. Often a simple change in housings and shrouds would deal with this problem inexpensively -- in the case of USB, all it would take is for the shroud to be a part of the standard itself, and the housing it mates with to hold and relieve strain on the shroud.

What about IEC cables? They're super rugged and virtually impossible to break. Proportionally downsizing that connector to be small enough would likely maintain the same level of ruggedness while being small.

I'd appreciate if people don't downvote me just because you disagree with me. That discourages useful discussion on HN. I downvote trolls and people who abuse the system with spam, not people I disagree with.

The USB-C spec is an insane mess. The fact that every port used to be different is actually a feature, as it helps you identify which device supports what based on the ports it had. If you see an HDMI port on a laptop you can be sure it's going to output some kind of video signal over that. If you see Thunderbolt then you're sure the machine supports Thunderbolt. USB-C just jams all these incompatible standards into…

You have to be a detective to track down which cable is compatible with which port on your computer. Of course most e-commerce platforms don't show features of the cable, it's usb-c and be done with it...

My experience watching a shop deal with transitioning to new Macs was that it was impossible to actually know a macbook+cable+device combo would work until you tried it. You could research all you wanted and there was still a chance it'd fail, or be glitchy and weird, unless you found someone with exactly the same combo to confirm that it worked fine.

Ditto dongles to connect to older devices. Will it work? No way to know, just try it and find out.

Last night, I was ready to pull my hair out trying to figure out what dock + cable I need, so this article is quite the blessing. However, I’m still left confused on whether I need a USB3.1 usb-c cable or Thunderbolt 3 cable. In light of the MBP16 announcement, I wanted to plan my purchase, including the peripherals. I currently have 2 4K monitors on a PC. I’d still like to use that PC from time to time, but it’d be…

I've wished for a universal thunderbolt/usb diagnostic widget or software for just these sorts of issues.

I wonder how many problems like this could be solved if people just had a bit more information about which ports supported which standards?

Once this is sorted out we would have a wonderful world. Using a single Thunderbolt port I connect my notebook to a dock and immediately convert the small notebook into a desktop with three external monitors plus many other ports. I can also magically use the same USB-C hub I use in the notebook in my mobile phone to add a keyboard and mouse plus an HDMI monitor. I have never seen this in the past: my previous notebo…

I tried buying into this, got burned. Dell XPS Dev Edition, top of the line Dell Thunderbolt Dock, should work great, I thought. Nothing but trouble, tons of complaints online, Dell refused a refund as it's "not defective" - it just doesn't work with Ubuntu well. The OS preinstalled on _their_ hardware. Most of the complaints about the Dell Thunderbolt docks are from Windows users, to top it all off.

My point being that the scenario you envision is now being sold by some manufacturers, but not necessarily delivered. These docks also have their own firmware, sometimes _multiple_ different firmwares, and at least those I've tried only let you update via Windows. There's UEFI updates that are supposed to help as well, again only updatable via Windows. So far, I can't say I'm super impressed with the reality of non-Mac Thunderbolt.

I haven't straight up broken any connectors, but my Pixel 3's USB-C port is super picky about what cables will fit well enough to actually charge. I end up plugging it in, flipping the cable around, trying again, moving the phone so the cable hangs slightly different, etc. Port is clean (apparently they collect pocket lint), tried 5+ cables, only the original one has a decent hold once plugged in. All this means I basically _can't_ charge my phone on the go, in the car, etc.

I can plug in a X1 carbon thinkpad in my monitor (some ultrawide dell) with USB-C support just fine. I then get video, audio, USB (the monitor has a hub where I have mouse and keyboard connected) _and_ charging/powering my laptop over a single link. Works today with Linux here! It's just magical, I tell you. The world started to happen already, it may not become all that good and 100% universal soon or anytime, but g…

I also recently bought a monitor with USB-C (Thunderbolt 3) which I can plug it's single cable into my DELL XPS and charge it, output 4K@60 to the display, and have my mouse and keyboard which are connected to the back of the monitor. The downside is when I want to use the same kb/mouse with my desktop, I have to unplug them from the monitor and plug them into the desktop.

Which monitor did you buy? I've been looking for one with USB-C support as I also have an XPS13. I have a 9360 and I know it uses a neutered TB3 PCIe lane (or something of that nature) so I'm concerned about being able to use a 4k 60 fps display with it. Have you had any issues? I use both Ubuntu and Windows on the machine, have you tried both with the monitor?

I think in future devices are supposed to support as many popular functions as possible. Due to trend of thin devices we need smaller ports and fewer of them. Multiple possible use of same ports helps. > As a user there is no easy way for me to tell the 12-inch Macbook's USB-C port is different than the Air/Pro unless you explicitly search for it in the tech specs Seems like manufacturer failure. > If you see an HDMI…

> Due to trend of thin devices we need smaller ports and fewer of them. People keep repeating this lie for some weird reason. Similar to the "3.5 had to go because phones are too thin for it" lie. Why? Why do you keep lying? What possible incentive do all these people have? Is it self-deception? "Oh yeah I'm totally fine with losing X, Y and Z because I get thinness and weight reduction in exchange!" You get neither.…

I think your use of the term “lie” here is a bit extreme.

> I miss the old DC barrel connectors -- they never broke, and they were usually designed such that housing of the electronics took the brunt of everything, not the PCB. I've patched up so many of these over the years, that doesn't really seem that accurate. Though it is relatively true for properly designed stuff (connector bottoms out on the case and not on the jack) and things using the rather rare panel-mount jac…

Agreed. We had a bronze PowerBook and replaced the DC socket on it over and over before giving up. Worse yet, the socket was underneath a bunch of stuff inside the laptop, so the process was even slower than it might be.

And then there's all the guitar pedals I make with chassis-mounted jacks... they can take an amazing amount of abuse.

Same for audio jacks. PCB-mounted 3.5mm jacks need resoldering often enough, but panel-mounted lasts forever.

I use the same solution (not hub like you, but USB 4x switch, originally intended for printers, with an extra hub for have keyboard/mouse). Not all brands work for keyboard/mouse, but I have several that do.
