From an article for this I remember one more interesting side effects of this approach - the flight computer ends up as a generic x86/ARM board that the engineers can just have on their desk during development. Previously the dev boards would use the same rad hard chips and would be as expensive and scarse as flight hardware, resulting in much harder development & engineers having much less experience with the real hardware.
