ThinkPad X1 Extreme gen 2. Bought it years ago. Very powerful laptop. Too powerful, it turns out. Burns through its battery so quickly it's basically impossible to use unplugged. At times, it has gotten so hot I burned my fingers on the keyboard. And sometimes it throttles to a truly glacial speed. The 4k OLED screen is gorgeous but eats too much power, and 4k is simply wasted on a 15" screen. On the other hand, it did survive spilling an entire mug of tea over its keyboard without any problems.
