Cool article! Sounds more than just a marketing concept to me... Some
thoughts...

* Desktop: What has been the initial idea of having multiple desktops?
Freedom of taste. To have different views (or frontends) into the
*same* system. I really like the term "Workspace", because it makes
this even clearer.

* The term "Desktop-Environment" emerged when more and more "system
technology" was pulled in, which created different frontends for
*different* systems. In my opinion a very unlucky development.
Fortunately, with newer technologies  (like network-manager, HAL,
D-Bus...), those mistakes have not been repeated.

* I like the idea to find a name for marketing the core libraries, but
i think "Platform" is still too close to "Environment". "KDE toolkit"
would be clearer. Because that's - what i believe - what it should
become in the long run: A convenience and portability-layer for
writing rich and beautiful GUI applications - but phasing out
system-technologies. Something like Qt enhanced.

* System (or Platform, or infrastructure) technologies like ioslaves
or kwallet: While KDE has been the "market leader" for a long time,
comparable technologies have caught up or have even become "cooler".
Therefore KDE could benefit from "incorporating" them. The "Platform"
should move to the layer below KDE - things that are eager to be
shared by everyone. You won't love me for that, but honestly: That
part of the world should be ruled by GLib and GObjects...

* And i also love the plan for KDE applications to become more "promiscuous"...
