Woohoo! Those of you unhappy with GNOME 3 now have a new choice available!
I've always had a soft spot for CDE, the first UNIX "desktop environment" I ever used (and I
still think it's better than any version of GNOME or KDE

).
You can get it here:

This is the real deal (not the castrated version known as
OpenCDE) from the Open Group itself. Way too late to make a difference now, but still nice to play with.
