It just works: Dell XPS 13 Developer Edition Linux Ultrabook review:
The remarkable thing about the XPS 13 Developer Edition is that it's so unremarkableit has Ubuntu 12.04 LTS installed out of the box, and it simply works.
It's an impressive achievement, and it's also a sad comment on the overall viability of Linux as a consumer-facing operating system for normal people. I don't think anyone is arguing that Linux hasn't earned its place in the data centerit most certainly hasbut there's no way I'd feel comfy installing even newbie-friendly Ubuntu or Mint on my parents' computers. The XPS 13 DE shows the level of functionality and polish possible with extra effort, and that effort and polish together means this kind of Linux integration is something we won't see very often outside of boutique OEMs.
Dell has done itand has done it righttaking its work and contributing it all back upstream for the betterment of the community. The company has elected to put a friendly Linux distro on an attractive piece of hardware with good specs, including a beautiful display and a quick SSD. Moreover, the price isn't at all unreasonable.
