Ubuntu 16.04 installed and runs without a hitch on a 4th gen (this announcement is of the 5th gen), with the exception of the LTE (needed to install a few libraries from 16.10), and the fingerprint scanner (which is apparently at the complete mercy of the hardware manufacturer Synaptics, no ETA there afaict). One thing to be aware of, though, is that support for Hidpi screens isn't quite as good as on OS X, so sometimes you're greeted by tiny text. Steam is a notable example of an app that doesn't scale properly. It looks like they included a different LTE chipset this time, though, so maybe compatibility is better there.
