A thirty-two bit extension and GUI shell to a sixteen bit patch to an eight bit operating system originally coded for a four bit microprocessor and sold by a two-bit company that can't stand one bit of competition.
While this is fun and can be seen true for w9x, it has never held true for the NT series. NT architecture can support multiple hardware platforms, and there have been versions for alpha, etc. These were discontinued, apparently due to business reasons. The design isn't based on DOS in any way. I suppose the 2bit company that can't stand 1bit competition could still be seen true, but that quote has gotten all its juice milked from it long time ago now.
