I jumped ship to MAC's/Ipads years ago but still have my Dad's old laptop running W7 and runs fine with some non networking programs that aren't available/compatible with IOS. The laptop is comparatively slow if used for inet browsing, which I never do anyway, plus I get prompts to upgrade for free to W10 but they can feck off!
We used Panasonic Toughbooks for proper outdoor "field" use for years when I was working, heavy and expensive but lived up to their name. Eventually they were replaced with standard "desk" laptops for cost reasons but they weren't up to the same use and probably cost more in repairs long term.
