People shouldn't have a problem calling this campaign for what it is - a failure. But also what matters is that it's not the end of the world.
I also am predominantly a desktop user, and would love for Ubuntu leaders to concentrate more on it, as i feel it was kind of a non-important project since Precise onwards. The market may be stagnant, but far from unimportant, as was also stated by dedoimedo in one of his articles. Making Ubuntu a great solution for professionals that are not software developers would be a great income - like architects f.ex. Those people pay A LOT for their work to be made easier.
