tl;dr: Can I install gnome 3 on ubuntu 11.04 and not worry too much? Tutorials say installing gnome 3 results in an unstable system.
I am using ubuntu 11.04, and although I am quite ok with unity (not so terrible after all), I would like to install gnome 3 to see if it is any better.
All the tutorials I find (such as this or this) warn that "the system might get unstable". But I can't find what is that instability they are referring to. What does it mean? Does it simply mean some tasks are more complex (such as getting software in the main menu for example) or really unstable (such as surprise reboots)? Does this instability stems from the fact that G3 is not a final release or some compatibility problem between ubuntu and gnome3? Lastly, is it possible to simply purge the package and get a stable system again?
