This was the 2017 14" X1 Carbon(not the extreme one). Mostly battery issues, it was holding up very less on sleep and in use. I was using Ubuntu and Ubuntu actually certifies the hardware. The keyboard was just plain awesome though. I don't think you would find a better keyboard in the slim form factor. Since this was an office one, I returned it and continued on my 2014 rMBP. It might have been fixed now btw. I will also try the newer X1s I can before finalizing on one.
