That I disagree with, on facts. None of the things that are present in activities overview are new or innovative. Hiding access to all those things was already done as well (and mostly without repainting the whole screen). So, no, activities overview does not solve any problems that have not already been solved in a desktop environment.
PS. As I stated many times, on some devices this kind of indirection is absolutely required. Tablets and especially phones have smaller screens, fingers as pointing devices which cannot hover or right click, so trying to squeeze "desktop control elements" on the screen there is not useful.
