I disagree. So there.
I use Ubuntu at home, with stock Unity.
The first time I encountered Unity, I was aghast. It was such a culture shock. The WTFs could be almost visible floating out of the room.
I tried Gnome Shell 3, sort of got on with it, but it wasn't quite right for me.
So, I persevered with Unity. Now, I wouldn't swap it for anything. I've used KDE from 3.5, Gnome from 2, E17, Openbox, fluxbox, LXDE, XFCE, and probably more I can't remember.
I find Unity fast, slick and efficient. I really do. Menus seem so old hat to me. Maybe you'll never like it, but I really see a future for it.
Here's Mr Shuttleworth's view.
