The rest now use KDE, XFCE, or a variety of apps under some standalone window manager.
My interest in Gnome was killed by the uselessness of Compiz, long before Gnome 3 was a sprite in the eye of any delusional developer.
I switched from Gnome 2 to LXDE (Fedora, Lubuntu). LXDE is simple, easy to tweak, and does what it is supposed to do. I don't even care what happens with Gnome. First they chased all the users with four video cards and four LCDs, then they chased all the users with tablets.
I have never, not even for five minutes, liked KDE. Some kManner of kRevulsion.
Maybe Gnome 3, KDE, and Unity will find success. Unlike you, the only prophesy I will hazard is that banks will make money hand over fist while working people lose.
The same thing is happening with Firefox, too. The productive users are fleeing it because the failed web designers
The recent UI dross that has been added to Firefox is of no use to me (nor to most people, I believe). However, it is still possible to ignore the UI dross and use Firefox productively.
Useless features could be a sign of delusional product management or developers living in their typical reality distortion field. Or both.
I think Firefox's release numbering is a bigger problem.
