Honestly laziness. Setting up a Linux vm works fine for light Linux apps, and ssh/rdp does everything that needs more processing power.
Given the Google web-drm thing I probably need to start looking at wiping it and putting Linux or FreeBSD or SOMETHING else but just haven’t felt like wiping a working system yet and reinstalling everything.
My current one? No, it's a cb5-311 with 16gb of storage, I could run an older arch, but only leaves 3-4gb after the OS install since no methods replace chromeos on this model.
