The fact that you can have the entire chroot or an individual app run in a window under xiwi as though it were a regular Chrome tab makes it even better. I regularly have everything running in ChromeOS except Sublime running in its own tab while I'm coding.
Someone else can probably chime in as far as how well it works if you want to go full-Linux on the thing.
FWIW, I believe Linus Torvalds uses a Chromebook Pixel running Fedora. 
Also, UX305FA is fanless. I love having no fan, hope to never again have a laptop with a fan.
ASUS Zenbook UX305FA-ASM1 model M (the fanless processor) gives me great battery life, and works nicely with Arch.
Of course, Microsoft has no idea, so the machine gets updated to Windows 10 and tries to send 60hz to the 50hz built in monitor, which decided (actually sensibly) to just blink at you until you fix it.
That was a great experience...
Those were one HP, one Lenovo, and one homegrown PC. So don't blame it on Dell.
There are lots of posts on the dell forums with steps to get linux installed on the XPS. The current developer edition is not supported on the latest hardware, 9350. Once the thunderbolt drivers are done they are supposed to release a new developer edition with Ubuntu. The dell Sputnik team posts on the forums regularly so you can stay up to date on the progress. They are fostering a very good community for linux enthusiast.
If/when the developer edition of the 9350 comes out over here in Rightpondia, I'll certainly be getting it.
If you want 32GB+, need a gaming notebook:
P series from Lenovo sucks for linux (keyboard and touchpad).
We are basically left with Asus ROG machines. They're very comfortable to work on and touchpad is great, but really heavy and battery lasts for ~3-4 hrs. However, they have a fast Nvidia card for neural nets + can run 5 VMs at the same time.
$1857 gets you:
i7 6600U processor
2560x1440 WQHD Screen
3 x USB 3.0
Starting at 2.6 lbs (1209 g)
Damn I think I might have just convinced myself here!
I use Arch and pretty much everything "just works," the camera, sound, wireless, etc.
It's rather absurd. Even the Nexus 9, doing light tasks, gets uncomfortably warm.

My S540 has an SSD,16gb ram and the slower processor and it churns through work fine, I mainly do Java development and on top of that I use the Play Framework which compiles to both Java and Scala so it's more CPU intensive.
I can easily run one or two IDE instances alongside 10+ chrome tabs,several terminals and mongo/mysql db GUIs.
It's by far the best 14" machine I found when I was shopping around last year. While it's marketed as a gaming laptop it also happens to be a fantastic general-purpose or development machine, especially since Linux runs so well on it. IIRC they recently announced the 2016 model which is cheaper and lighter yet.
Downsides are 1) it's expensive; 2) proprietary parts means no DIY repairs, and Razer requires you to ship your machine in for their very expensive in-house repairs; 3) the black/neon-green color scheme is a little silly, though it's not nearly as bad as pretty much any other laptop marketed as a gaming machine. I bought a round matte black sticker to cover the logo on the lid and it fits pretty well.
My 2012 blade went in for repairs several times and has the worst keyboard I've ever used on a laptop.
I don't know if they've improved their quality control any, but AFAIK they're still using terrible keyboards. Be careful and try one out before you commit!
overall good, decent battery(if you configure it right), but terrible wifi and broken cam(some fiddling required, possibly unstable hibernate), no sysrq
- Thinkpad X1
Probably the best support good battery, but no thunderbolt 3, so no external graphics, 16gb ram
- X260 Awesome battery, slower SSD than its competitors 16gb ram, good cpu, mobile broadband, only HD520 graphics(if it had thunderbolt 3 you could upgrade it with a discrete external GPU, shame really ...)
- Dell XPS 13, overall good up to 16 gb ram, Iris graphics, thunderbolt 3, so you could use a razer external discrete GPU(priced at 500 USD though). worse battery than the macbooks
- Surfacebook/Pro probably my favorite device, but linux support is flakey see:
Personally i'm still holding off i have a macbook retina 2013 and an air mid 2013. the retina screen died and i'm aching for a replacement but i want both graphics and battery, but that seems to be a no go. I'm leaning towards the x260, unless surfacebook magically starts working by the time i'm getting a new device.....
Managing docker-machines manually on non-Linux platforms was really starting to get tedious. Hoping this works as seamlessly as I imagine it would.
Regarding HiDPI: Gnome 3 and Cinnamon both work very well. I don't use many apps besides gnome-terminal, chrome, virtualbox, emacs, skype, and banshee. Except for Skype and Emacs, all of those worked with HiDPI out of the box. For Emacs, I just increased my font size. The skype buddy list is really small. I haven't investigated really changing it because I use it infrequently and it is still legible.
There has been huge variance in the build quality of the 2015 Pixels. I've had several RMA'd due to squirrelly disk controllers/flash devices failing (and disappearing from dmesg). There are common reports on the Google+ group of the keyboard rattling as well.
They are really nice machines when they work. The keyboard is great. The trackpad is great. The screen is gorgeous. The camera is good. Speakers are loud. Microphones are clear. The expansion is decent with 2 USB 3.1 Type C and 2 USB 3 Type A and an SD reader (unfortunate that the SD reader is USB2 and not USB3, due to all of the USB3 ports being exposed externally). The disk is undersized at 64GB, but acceptable for me to allow mobile development (This isn't a docker-friendly machine if that's your thing).
Linux Mint supports HDPI out-of-the-box, so that's what I'm going to try next...
For a more low-budget option the Lenovo L-series thinkpads are also pretty cool.
I went with 2015 model because I wanted the 1920x1080 non-touch screen to save battery.
Ubuntu on the XPS 13 was unavailable in the time period I made the purchase and I didn't want to deal with the wifi hardware issue.
One advantage of the XPS13 is a PCIe connection for the SSD.
You didn't mention cost, but the Asus will generally be a little cheaper.
I truly believe this battle to be between xps13 / retina 13.
I am not the biggest fan of the XPS 13, the few I have encountered all seem to have hardware issues of some sort. I bought one for my partner about 2 years ago (the developer edition with Ubuntu) and it had horrible screen whine that Dell wasn't interested in fixing.
