For me it’s also about reducing my reliance on my mobile. Teaching my kids by example that life isn’t only on my phone is easier when I can more clearly demonstrate what I’m doing. To listen to music I get my music device. When I want to take pictures, I grab my camera.
I picked up a used Latitude 7300 (I think?) last year and am quite happy with it. I appreciate that I can replace the ram and ssd myself for repair / upgrade.
I’m running Mint on it and haven’t noticed any problems.
