I’m now roughly six months into using Linux as my primary laptop OS, and it’s been a few months since my last progress report. I’m still using the Dell Latitude E7370, which continues—from a hardware perspective—to perform admirably. CPU power is a bit limited, but that’s to be expected from a mobile-focused chip.
