Thanks for the recommendation, I've been seriously considering one of these for my XPS.

As a side note I am deeply in love with my XPS 9310 (Tigerlake) on Kubuntu (kernel 4.11). Battery life is INSANE, instant wake and sleep, keeps cool, but still has thermal overhead/power (thanks to the fans) to do large kernel compiles or other serious hard work. Also the screen (I got the non-4K model) is very pretty, sometimes I just look at it and go 'wow, that looks good'. Excuse me if I gush too much.
