I will say that the demonstration items that Nikon shows for it's Capture NX2 software are very impressive. Impressive enough for me to download and give it a try.
After 30 minutes of playing with it... I'll say this... I'm not paying for it... yet.
I think that buried in there somewhere are some good, if not great, tools and functionality... that I'm obviously not going to get to in 30 minutes. I'll keep playing around and seeing how things work. Maybe I'll figure out more about the u-point / control point thingy and realize the error of these comments. But 'till then, I'm not paying for it.
However, if you don't have an image editing program, or are looking for something to handle your raw NEF files... I'd say go for this over Photoshop any day... but look at ACDSee Pro as well.
