Nice site. . . kinda interesting to me to see how little the windowed environment has changed over the years. Granted there have been improvments on asthetic elements of the GUI such as number of colors displayed, backdrops, shadows, etc, and the processing power behind the systems but functionality really hasn't been improved upon since the really early days once icons, gadgets, windows, and menus were developed.
It would be nice to see something really new as far as UI design is concerned to come, (and I am not talking about melting windows like in MacOSX or crazy spinning and warping windows like are planned for longhorn.
Still an interesting site I had a good time looking at.
