We take photos for our and other's eyes, so what better criteria?

"Horrible noise and artifacts!?"
Those problem pixels locations are lost on me!
My .27 mm dot pitch cathode ray tube monitor CAN be set at 1280 x
1024, but IS set at 832 x 624, so I can make out the pixels and other
little items on the screen, and the kid's blemishes do not stand out
for me!
Maybe I should save up for a new Sony LCD monitor, and get some new
eyes?  ;^)

That crop, with both kids, displays at a little over 10" wide, on my
screen, while the same area (width) from the original jpg measured at
about 12" or a shade over, as I recall.
But, that's beside the point, as I _still_ can't discern any gross
problems with your crop of that image!

Now, I blew it up to 200 and then 400% of the original 2048 x 1536
image, so as to make the boy's head measure 5.5" top of cap to chin,
and now I start to find pixellation at the top of the boy's ears
(highlights?) and top of her turtleneck fabric.

Maybe having to blow it up that far to see it is a good thing! 
When I get my Optio 550... or will it be the OptioS ? I'll just have
to hope they display as well at the same resolution.

Let's hope it isn't, and you get to keep it!
