This is one of the most widespread and major misunderstanding about computers. Computer science is not about computers; Just like astronomy is not about telescopes (Dijkstra). The only thing that really matter about computers is that they are communicating Turing-complete machines. Every communicating Turing-complete hardware on the planet is therefore the same, modulo the necessary emulation layer (performance is becoming secondary, so let's pretend it's not a problem). What we want as humans is communicating Turing-complete machines that are easy to use. That's a fact about us, not about hardware. Therefore, OS APIs should depend on us, not on hardware. Having an OS whose API is influenced by the actual hardware is a pity. Making an OS whose API is influenced by the actual hardware is a shame.
