Actually, precision and robustness. It's better to have one camera take
three different pictures with three filters than to build a camera that
takes three pictures at once.

More likely payload weight. That thing has plenty of cameras on board -
many of them designed for special purposes for which resolution is more
important than color. This particular one, for instance, is intended for
navigation purposes - most likely a wide-angle camera; but the
scientists have enough panorama color shots from the Mars surface
already, so they went for the lighter alternative, and only have color
on some other camera designed for close-up shots (as close as 2 cm or
so; it can focus at infinity as well though). We'll see full-res shots
from that camera in due time.
Remember, this is not a sightseeing trip - it's scientific exploration.

I did not even imply that but it was in my mind. It was at the start of
this phase of the mission and I suspect that there is more need for the
bandwith than sending postcards home. :-)

Testing all the systems is probably the current top priority ATM, so
aside from some hi-res postcards from each camera, they'll also want a
nice greeting from each and every sensor, actuator and any other gizmo
onboard, yes.
