I've been using an X1 (3rd gen with the 4K display) for about 2 years now I think, and it's a great laptop for Linux. A full charge will last around 8 hours, maybe 9 or 10 if you turn of Chromium and WiFi (this all depends a bit on what you end up doing). My only complaint is that I had my display replaced 3 (or maybe already 4) times either due to dead pixels, or these white smudges on the screen (these appear to be caused by damage to the LCD). These smudges in particular keep popping up and aren't too uncommon amongst other users either. There's a new one since I last had my screen replaced, but it's fortunately only visible when looking down on the laptop from the top (even then it's hard to see).
