Although this is now an obsolete model, I thought I would add a comment in case anyone was considering buying one second-hand. My workplace issued me one a year ago and it was a lightly used year old one back then. I tend to use it docked to a screen and keyboard.
The screen is good, the keyboard and touchpad fine. Audio from the speakers is OK for radio/speech, and the audio from the headphone jack is clear and decent and free of interference.
The laptop has stood up well to commuting daily to the office, wrapped in a thin sleeve, this has tested the HDMI, usb-c, headphone and power jack with over 400 insertions and removals and still working fine. So I would be happy to recommend one as a second hand buy if it's been taken care of. Mine has survived a few drops of about a metre onto a carpeted or wooden floor and there's barely any cosmetic indication of it.
It's possible to use a USB-C combo hub to get HDMI, network and USB ports, the right hub with USB PD means you can charge the laptop too. This works well with a 4K monitor. The USB-C isn't thunderbolt. I am using both the HDMI and the USB-C to HDMI hub to give me twin screen 1440p displays.
I'd say the biggest downside is the thermals. Mine has the i7-8550U processor, and the fan runs at a clearly audible volume once you sustain 15% CPU usage or higher! When running windows, this means the fan runs all the time, with linux it's a little more subdued. In fact, when I got it, I though something was wrong and part dismantled it to check the fan ducts weren't blocked, because it seemed thermally throttled!
I run linux on it (Fedora) and it runs well, but, suspend doesn't work. I found thermal throttling was a problem, so I disabled hyper-threading since there was no performance gain at all, it can't even use four cores sustained at full speed!
So if you're offered one in good condition at a good price, with i5 processor (true quad core or better), nvme drive and at least 8GB of RAM, you should get a decent work horse which will last a decent length of time.
