Your kids might not want a hand-me-down computer, but if you have a recent-vintage notebook to spare, then they should take that, because you know its history. Year-on-year, computers don’t really change that much. Even a five-year-old laptop is capable of anything but the most demanding of video-editing tasks or playing 3D games.
In fact, in a modern laptop, there’s not much to go wrong. The screen hinge, the keyboard and trackpad, and the internal fans are pretty much the only moving parts.
This machine doesn’t have to last forever. It only has to run until there’s a supply of new machines to replace it.
