My main desktop is Ubuntu GNOME 16.04, which I guess is now just Ubuntu. I think it’s great. The author of this article seems to think heavy-duty Unity users will have some trouble adjusting to GNOME. Maybe I wasn’t enough of a Unity power user, but it seems like a very easy transition to me. Unity is a failed experiment, but it did help give birth to MATE and Cinnamon, so some good things did come out of it.
