I don't disagree. I have a soft spot for the Newton because I had a lot of respect for Larry Tesler, who got Apple interested in Common Lisp for a while as part of the Newton project. CL was used to invent Dylan which was originally intended as the Newton programming language. Dylan ended up like the Newton: The invention itself didn't have much impact but the project and the people who worked on it moved computer science forward in many important ways.

Oh, and the genesis of what we now call the ARM computer architecture was the Newton project.
