I used System76’s Pangolin for weeks, and Linux was not the biggest problem

After using System76’s Pangolin as my primary work laptop for nearly six weeks, I can tell you this: If you need a 15-inch Linux-focused laptop, this is the one to get.
The Pangolin is a solid device, designed more for dependability and convenience than ultrabook portability or cutting-edge parts, but it still has reasonably modern hardware (especially its 144 Hz screen). The Pangolin and its native Pop!_OS are a showcase for how remarkably normal Linux can feel as a daily driver in 2023. Normal, and with lots of ports.
