So, there are lots of things to be said about Gnome 3.0. A lot of cruft was removed everywhere inthe stack, several applications gained massive UI changes, (Still not sold on the navigation arrows placement in the file manager, but that's me).
The most "in your face" change is the shell, which will polarise a lot of discussion, opinion and people. Looking forwards to it. It does rehaul something that has been static and comfortable for a long long time, in the process of changing that, several things went missing or were not reimplemented in the same way.
Both for good and for worse, I'd say.

I'm looking forwards to seeing where this goes. It's a change, and change is never all easy.
