"Way more functional", being relative, isn't saying much. I use NX to convert d300 raw to .tiff to edit in photoshop cs2--The only reason I have it. Once I upgrade to cs3 I can set the light and dark points like I do with my d70 & d80 raw files in cs2. Then I'm going to delete NX from my hard drive and go take a shower to make sure I get it all off me. I love their cameras, but refuse to support their, "No retarded software engineer left behind", program. I'd rather pay $200 for a CS upgrade than get Nikon software garbage for free. AND, it doesn't hog any resources if you don't have it.
