At this stage the key differentiation point is touch (ie. your finger as the pointer) v. the pointer (mice/keyboard, etc.) The UI for these two categories is naturally different, and convergence would be possible only when the UI can handle both. Even in the case of notebooks with touchscreens, the UI has to handle both requirements well, that of the finger and of the mouse/keypad. I personally feel Ubuntu is neglecting the latter. In time, that may well be the right choice. At present, it's definitely only part of the story.
