If your use case doesn't require a lot, it's not really going to matter mac or windows... If you're spending the same amount of money. I have a 2010 Dell m11x that's just fine for productivity. It was $900ish then.
I just use an old -2012- dell mid tower. I have jank dust collection if I even run it. It's survived for 5yr and wasn't cleaned out after it's first life in an office for 7yr.
Saw dust is easy to deal with in a desktop.
It's oily substances that are more problematic.
Pretty cool video. Thank God for fast forward... I had enough idling around similar stores as a kid.
