It's an article in Technology Review about "revitalizing the tired old desktop metaphor". Now, while it probably could use a good revitalization, I'm not about to pronounce the desktop as we know it dead.
I've been reading a lot of this sort of thing of late and I find it interesting. I hope you will, too. Please either follow the link in the article to "Bumptop" or use this one.
I also found a sort of history of interactive desktops and/or Graphic user interfaces (GUIs) here that I think you might find both interesting and thought provoking.
