The X1 Carbon has a Skylake CPU, so the problem that Linux doesn't have support for the higher C-states resulting in reduced battery life and reduced total CPU lifetime should apply to you, right??

(I have tested the predecessor (gen3) and liked it. I'm waiting for the 16GB gen4 X1 Carbon to become available here in Germany, drop enough in price to be affordable, and for Linux to support all the C-states.)
