The red and blue inks are only for color prints. This has no effect on B&W,
but some of us print color, too.

As to dot size, I believe the 1280 and 2200 are 4pl, but the R800 and new
5000 printer are 1.5pl. In theory, the smaller the dots, the closer together
they can be placed for a given darkness, meaning less grain and sharper
detail. However, using stock color inks, this may not mean less visible
dots, because they're using the smaller dot size to allow them to drop the
light versions of C, M and K inks.

If someone comes out with a B&W inkset for the new printers, the smaller dot
size could render sharper detail, although I think even the 1280 and 2200
reach the limit of what my eyes can discern, too. So I think the main
benefit of the newer printers is for color printing.
