I read this post about the desktop computing metaphor and when I read the description of an itemized operating system my experience with the NewtonOS immediately came to mind. What I remember is that everything in NewtonOS was an object and data was separate from objects so that you didn’t need duplicate data. I am probably not doing the topic justice, but I do believe NewtonOS was the only “object oriented” operating system that I have ever personally used. Regardless, I really would like what is being described in the post because I agree that the desktop and window metaphor is no longer the best way for us to do personal computing.
