>Unix generally has the correct basis for the design.

I can't disagree with this more, Unix is broken in so many ways and its designs continuously cause me pain. I would not describe a modern Linux or BSD as "simple", maybe the core of it is, but to actually build a modern OS there are so many layers on top of it. And when you do that, the crumminess of the foundation really starts to stand out.
