It seems at least reasonable to try to compare smartphones to the innovation of the microcomputer. Mainframes/supercomputers have a particular purpose. When microcomputers/pcs came along, they filled a new purpose, but they didn't necessarily try to replace everything workstation and mainframes were doing for a very long time. They will never do everything that a compute cluster does. The same will likely be true for desktops for a while. I imagine that mobile phones will do much of what desktops do eventually, but it's going to take a long time to get there.
