I'm running Ubuntu for a long time and many of my students at our University switched from Windows to your great OS after my lessons.
But after that forced update to Unity you lost a lot of fans. Many students came and asked what they should do. We tried Gnome Shell (it's much better than Unity) but it could not nearly compare to Gnome 2.x!
If you go your way with Unity in future you will only help Microsoft and loose the leadership in Linux distros. Please give us Gnome 2.x back - as soon as possible!
