Finding one with a decent screen for anything other than gaming is the trick. I linked it up there, but this is IPS with 100% sRGB, more brightness than most people need, 16:10 (vertical space is nice!), 165Hz, and matte! Most gaming laptops are...not that. Maybe 50% sRGB on a dim glossy TN screen.

Workstation laptops from Lenovo and Dell have upgradeable RAM and have been offering 128 GB RAM for something like 6 years.
