It's already braindead easy to put Linux on the ARM Samsung Chromebook. One of the first things I did was to assemble my own personal Linux distro and besides having to copy some blob files out of the original ChromeOS image, it's all very straight-forward stuff and I pulled up about a hundred packages I wanted including an X.org stack without fuss. The compile speeds are adequate if you aren't cross-compiling, I've certainly put up with worse.

I personally have little interest in the Pixel based on the specs. I think X86 is excessively 'big iron' now for a majority of needs and I find the lack of USB3 is mystifying. The screen looks interesting, but it's nothing I actually /need/ and certainly not worth another thousand bucks. I've personally taken to just using X86 for storage/cross-compile servers for the rest of my cheap ARM/MIPS/etc. crap and I've made it a point to stop buying expensive hardware. What $250 buys you now is actually pretty ridiculously awesome.
