The only downside is that some things in MapSource are
defined in pixels, and they get REALLY TINY at that res.
But that's a SMOP (Simple Matter Of Programming), or, better
DON'T EVER DEFINE ANYTHING IN PIXELS.

I also had a chance to look at some 2M resolution bathymetry
of my favorite dive sites. It was a combination of vector
data (contour lines and bottom type) and raster data (the
details of the bottom, and an overlaid nautical chart). The
vector data looked great, the details (at 2M res) were OK,
the chart, where a pixels was maybe 5M, was badly pixelated
(that's solvable with either vector charts, or a higher res
raster scan.)

While I don't think we are going to have 22" displays on the
console of our whalers, an 11" HD (1920x1200) display would
be really impressive.

BTW, that display is about five years old, and was about $10K
new.
