This got me thinking. It appears the only gripe I have left is addressing Unity itself in some way. As I stated before, I have no problem with Unity being among the available desktop options. But defaulting people automatically to it is just plain foolish. There should be a cleaner indicator for folks that GNOME's classic experience is still available.
Sadly though, users must rely on their past Ubuntu experience in working with multiple desktop environments (or use Google) to learn that this is even a possibility.
