I wiped the factory 14.04 install when I saw the number of error messages during updates. I've been running 16.04 daily builds, and the only perceptible issue (screen flicker/blanking) was resolved in 16.04 final. There's a bios update which, although its release predates shipping, must be applied by users. (While still on factory 14.04, plonk the executable in /boot/EFI then reboot, F12, bios flash update).

Dell don't appear to have updated their Ubuntu repositories for 16.04 but the necessary hardware drivers appear to be present in 4.4.x kernels. The same goes for Intel's Linux driver tool, but this also works out of the box on 16.04.

I'm waiting for Amazon to deliver a USB 3.1-to-HDMI cable so I can test video out.
