But the Pi probably costs less once you factor in energy costs, no?
It's great that it did not become ewaste, and a computer you have is better than one you don't have, but people likely shouldn't pick up old netbooks over something like a pi.
If you used one for something equivilent to a pihole then I think yes it would cost more over time, although we're likely talking many years of 24/7 runtime for it to then become more expensive, the low power x86 chips are a lot more efficient than they used to be.
