I'm running Arch on a Dell M3800, most of my colleagues are running various Ubuntu flavours on the same hardware. Works well, up to and including the touchscreen.
Battery life is poor compared to a Mac, but it's really light given the compute power.
I have had to replace the screen on my M3800 twice now in one year (it develops two shadowy lines on the screen), and there are some other issues that I don't like; The "sound card" had an bug that makes it give off a quite noticeable white noise. It also has a slight coil noise that I'm not a huge fan of.
