Seems I am in a minority, but I like gnome 3's simplicity.
I don't like how much resources it consumes, but I can not have everything.
I like gnome 2 as well, but I decided that I should not be wedded to any particular GUI and that I should use different ones to maintain awareness of strengths and weaknesses.
I have used Unity, mate, gnome2, gnome3, xfce, kde (not so much) and I try others from time-to-time, but I seem to prefer gnome3 right now.
If Gnome had supported both v2 and v3 I suspect no one would care, but they seemed to abandon v2 and that upset it's community.
Gnome 3 does have a fallback mode that seems very close to v2 in look and feel - is this so bad?
