Windows has historically sported better system integration than Unix, with system components of greater granularity and flexibility than Unix has historically provided thanks to the power of COM interfaces. If the tightly coupled Windows way provides a better solution, then maybe we should build things the Windows way.
nothing that you said is actually true. There are probably 10,000 Unix systems for every windows system now, and all of them support far greater granularity and flexibility than any windows device has ever offered.
