The Common Desktop Environment was created by a collaboration of Sun, HP, IBM, DEC, SCO, Fujitsu and Hitachi. Used on a selection of commercial UNIXs, it is now available as open-source software for the first time.

I absolutely love this desktop environment! It's my favourite, and I use it every day for almost everything. I still use MATE for some things, but CDE is my main one. Once it's more polished, I'll likely change this to 5 stars. Tip: If you play Minecraft, it runs better in CDE than any other desktop environment.
