Small form factor and all-in-one will ensure that desktops never quite disappear. Heck, the all-powerful bleeding-edge no-holds barred desktop will always have a place somewhere. Anyone who programs or creates content will want as much screen real estate as possible.
To really see a disappearance of the desktop will require a revolution in user interface and display technology. So long as we're still doing stuff that looks like working on a "workstation" from the 1990s (or Xerox Parc in the 1970's) we'll still have desktops. I guess that's almost tautological. We'll have desktops (computers) so long as we have desktops. (The table-like places to sit and do our work)
