[GTALUG] Anyone ever use System76 laptops?

Hi I understand that System76 laptops ship with Pop! OS, so I was interested in getting my hands on one. Has anyone on this list had any experience with these laptops they might like to share? I was thinking in particular of getting a Pangolin 16" laptop, and would it support my portable Lenovo ThinkVision M14 monitor? I already have the monitor, and in theory (according to the docs that came with it) it uses USB-C. If a monitor says it uses USB-C, does it need external power? Would a laptop with a Thunderbolt port be better? Paul King
