I own the 4870 non-pro version. I believe the difference is in the software 
that comes with it. I purchased mine from NewEgg.com for ~$400 a few weeks 
ago. It's worked great for me- this is the first scanner that I've owned 
that's had dedicated carriers for 35mm negs (24 frames), slides (8 frames), 
6x6 strips (6 frames) and 4x5 film (2 frames). This eliminates 'Newton's 
Rings', since the film is slightly suspended above the glass platen. I 
can't compare it with "(see above)" except to note that the resolution is a 
bit higher, and to speculate that the active transparency scanning area may 
be smaller on the earlier model. The 4870 also uses the 'Digital ICE' 
system, which does a pretty good job of eliminating dust, scratches, and 
other opaque crud. Note that since 'Digital ICE' relies on the IR 
transparency of film and dye layers to work it does not function on 
silver-based films.
