FWIW, although I only ever got to do very little pair programming (and it's long ago now), from all I heard about it (and the way it worked for us when we used it), I've got the same impression as regularfry and twic: It's at least as much about the actual code produced as any knowledge transfer. Seems to me that it has suffered the same fate as so many other original "Agile" practices: The image of them nowadays is gravely distorted, sometimes to the extent of being a caricature, of what they originally meant.
