I am reasonably happy with my current desktop being Gnome.
I have seen and read plenty of posts regarding the new Unity desktop and its apparent faults or limitations of functionality.
Now that my machine is announcing that 11.o4 upgrade is available, I need to know whether it will change my desktop to Unity rather than keep the existing Gnome (with its more familiar functionality).
Will I even notice? Can I easily switch back to Gnome if I don't like Unity?
Can someone who has done an upgrade please advise.
