Both Unity and Gnome 3 have both taken steps that degraded usability for the sake of looks.
Gnome 3:
You can't log off, as if we were using a tablet and had unlimited resources.
Having more than one window open is hard.
The windows are not side aware because that's what you have in a tablet.
If it weren't for the hot corner, it would take one more mouseclick to do almost everything; now you must constantly take trips to the screen corner.
Clicking on a minimize/maximize button is faster than double-clicking on the menu bar.
There is no parent/child organization of programs by type; there is no organization period, so the user has to type in multiple searches.
Unity:
Ubuntu with Unity's footprint is almost twice that of Gnome 2, and for what?
Menubars are hidden for the sake of appearance.
Unity is subversive to Gnome, on which it depends; this is a suicide attempt.
Please, everyone do not use Unity, just because a marketing person puts it on a disk doesn't mean that you have to use it.
Both Unity and Gnome have taken steps to disempower the user for the sake of looks and constricting the users actions all to force a method of using the computer which is not sound.
Hand out the impeachments.
