After using this plug in for a few weeks.... its not as flexible as Nikon's Capture 3, nor do I think the quality of the images is quite as good, but still it is very useful. For day to day, I'll go with Adobe, but for the higher end stuff, I think I go back to Nikon.
Who knows, maybe Adobe will update it. Nikon Capture totally sucked before it was updated to v.3.
BTW: not real impressed w/ Bibble. (another 3rd party RAW converter)
