By from scratch I mean not following an existing design as a blueprint, I'm not talking about reimpleminting an existing API based on existing API specification.
You take a white page and design the all thing, you can of course borrow ideas from others that you know work and build something new for the better, because existing OSes do not satisfy you entirely.
The work done by the Morphos team might be on par or beyond what CBM did but I'm wondering what you think of the work done by only one, read SkyOS, too bad it's not developed anymore (Just read an interview of the author he seems to have earn a lot of money creating games for the Iphone, so who can blame him). At the beginning Atheos now Syllabe was also done by just one man as a AmigaOS successor.
