Any time I design a laptop into, say, a robotics system, I have to buy at least a dozen spares and store them away, because five years later when the laptop dies and a $500,000 machine that generates $1,000 per hour in profits goes down, that model of laptop will no longer be available. With open-hardware like Novena, I have a good chance of being able to make a new one that is compatible five years down the road, and can get by with two spares in storage.
