The worst part of using a gaming laptop on Linux is that, despite the great work of open source developers and hobbyists, it's still way too clunky to use a hybrid graphics setup imo. Once you want to use an interface that's only connected to one GPU (such as HDMI) you're left messing with switching utilities like optimus-manager which (while very useful!) are usually rarely updated and may not work on certain systems.
At least with a system like this, which is pretty similar to how much I paid for a 1650Ti-mobile (while being faster!) all the graphics are handled by a single driver, which simplifies most of the pain in using a laptop on Linux for anything graphically intensive.
Looking forward to seeing Framework becoming this affordable one day, because I'd much rather go with them over Lenovo, but at least for now I can use Lenovo which lets you refuse Windows and save £90 :)
