I want to get stuff done on the desktop. The less tweaking I need to do the better off I am.
The odd part about bitching about customization is that Gnome 3 is actually FAR more capable, flexible, and open to modifications then Gnome 2 ever could dream to be.
'Linux power users' shouldn't need pages and pages and pages of tick boxes and confusing dialogs to be able to customize their desktops. People who are not power users will just get confused and lost with such horrible configuration GUIs.
Let KDE be KDE. I don't want Gnome 3 to be KDE. There are good reasons I have no desire to use KDE at all. People that like KDE can stick with it and count their blessings.
