I second that. I only use X1Cs. Had a gen3, gen7 and currently use a gen9. The one I have now (X1C Gen9) is the first one that turns the fans on without any CPU heavy task (compiling, blender, stuff like that). Low RPM, but fanning nonetheless. I throttled the CPU ([email protected]) to 2GHz (the hardware limit is 4.7GHz), and it no longer heats up; bullet dodged.

The gen7 had a screen malfunction, repaired under warranty with flawless service. I just upgraded because it would take two weeks for service turnaround, and we might as well have a spare laptop around.

Excellent keyboard, much better than Macs. I use trackpoint, so I'm unable to evaluate the trackpad. The internal display is 1920x1200, and I have nothing bad to say about it. Excellent linux driver coverage. Runs cool, even if it required capping its performance.

I have the X1C gen 7 and love it, has been a wonderful machine for me. It's my personal laptop, and I do most of my personal development on a desktop machine, but it sees use many days each week. I'm running linux. I haven't had any complaints about this machine whatsoever.

How is the battery life?

I get 5-7 hours on battery from my X1C7 FHD running Ubuntu. I carry a power bank in my bag that gives me that much again.
