To a new eye it looks like that Dist-Upgrade & Upgrade (should) do slightly 
different things

Dist-Upgrade does as it says to the  distribution, i.e.
the stuff that came with your flavour of Ubuntu (or was added to later Dists)

Upgrade does anythiong that was added/installed by user via apt-get (or the GUI 
eqiv)

I might be wrong ?
