This is really fun work that takes me back to the very early Newton days at Apple. It is a little sad that in the past 30 years we haven’t made more conceptual progress on what pen-based tools should be. It’s like Ivan Sutherland opened a door but we can’t seem to walk through it. It’s not a hardware problem — pretty much these same demos could have been done (we did some of them!) in 1990 with much more primitive devices. It’s more that we haven’t found the underlying model to build on to get beyond simple demos.
