Gnome 3 now gives you much more ease, confort, and control. I tested it today and I really loved it. Mostly I worked on black and white screen but this one gives me satisfaction.

Gnome 3 has been now revamped. Also, now the cloud services are seamlessly integrated.

Ubuntu’s own interfaces is impressive too, but if you want to test out the gnome3, you can do so by following the step given here.

Now reboot, and enjoy!

Above is not officially supported upgrade method. But that worked for me, many others.
