And you can also argue that that's overengineered (the original NT design docs were posted on here a while ago), that the UNIX model (while much more primitive and simplified) has proven more successful in the real world, and that the original "clean, overengineered" NT design has been buried under a progressively bigger truckload of crap year upon year and is no longer as clean as it once was.

The original UNIX model has (considering the current state of GNU/Linux) similarly buried under a progressively bigger truckload of crap year upon year and is no longer as clean as it once was.

A central difference is: the NT kernel stayed rather clean (the crapload rather happened in the Windows subsystem).
