The Graphical User Interface History

Screenshot provided is neither GNOME nor KDE, it is WindowMaker. Most screenshots in the article have terrible resolution. A better site to see history of GUI is: http://toastytech.com/guis/index.html
The article constantly misspells "X Window" as "X Windows" which for anyone who has even a small interest of GUIs through the years may find incredibly irritating.
But the cherry on top is the absolutely outrageous lie that OSX was introduced with the Mac transition from PowerPC to Intel. This is just ridiculous.
I don't know much of the other GUIs and I can not comment if they too were horribly represented.
And of course, iOS and Android.
There is definitely a market gap for devices like the old The Psion 5MX. i.e. A ultra-mobile device with a really satisfying keyboard experience.
There is no mention of PLATO[2] whatsoever.
And I stopped scanning. Maybe this is intended as a "personal history" of GUIs, but otherwise, it's lacking.
Since we're all recommending things for inclusion, I think some nod to the new breed of tiling Window Managers like i3 might be good. By dispensing with the desktop metaphor and de-emphasizing the mouse I think they're a significant departure (to me they are a little like the expert UIs mentioned by Engelbart).
That page you linked for the Mother of All Demos is a nice jumping off point.

[EDIT: Also, buttons had rounded corners. HTH did Apple get a design patent on rounded corners?]
(Anything is better than the 4-colour-CGA Windows ≤ 3.x interface, though.)
