Nikon's NXCapture Software - Opinions?

Just wondering whether anyone here uses Nikon's NXCapture software for
photo-editing/manipulating. If so, are you using it just for RAW, or
for JPEGs too?

I downloaded the trial version, but haven't had a chance to really try
it yet. - Maybe later tonite if I have time. Reading thru the website,
the interface looked pretty unique.

Finally, does this software come included with any of the Nikon cameras,
or is it strictly an add-on purchase?

Thanks!

I very much like NX as a raw converter. I generally open images in NX and
then finish in Photoshop.
I like the default settings that NX opens raw images into; NX also allows
adjustment of the levels and curves directly, something that is obliquely
done in the CS3 converter.
The control points do not allow as fine control as, and are no substitute
for, layers. However once you get the hang of them, if you like the
paradigm, they allow for very rapid optimization of most images.
One problem, to me, is that NX defaults to 16 bit color, something I have
issues with and which massively increases file sizes for very little
practical gain IMHO unless your object is a smooth histogram instead of a
print.
Whether NX is worth what Nikon charges for it, however, is up to the buyer.
It's kind of pricey for what it is. The same can be said of DxO and Phase
One: if it works for you it is worth it.
However if you could only have one program stick with Photoshop.
