I've used this model (same config as reviewed-except I have the PCIe NVM disk) for about a month now and can confirm pretty much everything in the review with a few exceptions.
I have not experienced any of the "coil whine" mentioned with my unit. Fan comes up to barely audible only during sustained max-load conditions. So I consider it to be silent for practical purposes.
The "black soft-touch paint finish" feels great and looks great (when clean)... However, if fingerprints really, really bother you, this is probably not the machine for you! As stated, it is a fingerprint magnet. They bug me, but I'm learning to live with it as I otherwise love nearly everything else about it. A wipedown as part of my daily routine has gone a long way to keep it tolerable. The same problem exists with higher end Lenovos with the similar finish.
Speaking of fingerprints, ironically the only significant issue I've had is that the fingerprint sensor (for login) only worked intermittently. Dell dispatched an on-site tech with a replacement part, but he said he corrected a sensor cable issue. But it is still not working right, so I guess I'll have them back out and ask them to replace the sensor this time. Despite not being initially successful, I've otherwise been impressed with the courtesy and speed of the Dell service process. The phone dispatcher took my issue seriously and made arrangements without any of the scripted or condescending type of treatment you sometimes get from tech companies.
They even gave me the option to replace the part myself... which I certainly would have in most cases... but I had declined and opted for the included-in-warranty on-site service because of all the parts, the fingerprint sensor is the most difficult to replace as _everything_ else needs to come out of the unit. Otherwise, I did take the back cover off and see that all the main parts you'd want to replace or upgrade like RAM, SSD were readily accessible.
Other than these caveats, I've been extremely satisfied. All day battery life (with rapid charging), 16GB of RAM lets me keep lots of apps open, the PCIe NVM disk is plenty fast, keyboard and screen are excellent. Enough horsepower for software development work while docked at my desk, but plenty portable for the other half of my job where I'm going between rooms and buildings to meet with people.
Would choose again.
