This article is four years old - a terrific predictor of today, through the future. Obviously, the author couldn’t have known that Canonical would eventually relent on its insistence that us traditionalists would all ultimately be transformed into Unity adorers.

When I was young, here in the American South, we had CocaCola; and we drank few other softdrinks. One day some naive well-wisher took away our CocaCola and replaced it with the awful tasting "NEW Coke." The rest of story unfolded in a very similar fashion to what we have now have with our beloved MATE; it's just called CocaCola Classic in this case. You just cannot stifle the thing that proves to do the best job - no matter the gimmicks and marketing strategy.
