One other thing that impresses with the Newton is that everything is linked. You had "soups" which held various bits of information, such as addresses, and made this information available system-wide. So you could write a third party app that could access this information, without having to double up and enter it again. I'd love to see more of that in the IT. It really opens up the scope of what the IT can be used for, rather than just surfing the web or playing a video.
