I'm considering an Epson 4870 for scanning 4X5 negs. How flat does it hold
4X5 negs?

I have an Epson 3200 which is very similar. The 4 x 5 holder clamps
down on a sheet of film reasonably well, but there is still room for
some sag in the middle. The Epson scanners have fixed focus lenses and
rely on depth of field to keep things in focus. The ideal position
seems to be about 1 mm off the glass, but considerable variation is
possible without any obvious differences. I don't worry about flatness,
and my scans are quite sharp. If you want it to be flatter, you
probably have to hold the film between two pieces of glass. One could
be the scanner glass, but then the film would be a trifle closer than is
optimal.
You are not likely to do better for 4 x 5 without spending a lot more.
