If you're really concerned, you can buy two $100 secondhand laptops. If one fails, you can use the other. Good secondhand laptops in that price range will be more like 8 or 10 years old, but still usable as basic daily computers.

I've had an excellent experience using secondhand business-class laptops. Several nonprofits I'm involved have nothing but these sorts of laptops, and I've only used secondhand laptops since 2019.
