I have been using this program extensively for several weeks and for the majority of my photos this is all they need. The program is non-destructive, lets me change my mind about one part of a change without having to go back to the beginning, lets me use the histogram if I need to, and in general allows as much or as little tinkering or editing as I need. Sometimes I will Save As twice, once as the jpeg that I can move into iPhoto if I want to and once in the PhotoComplete format that retains the picture's transformational history and will let me tinker some more if I want to (or have the time to.) It does not replace either iPhoto or Photoshop for some functions (red-eye, for instance, or spot color correction) but it does much that iPhoto doesn't (and with the added benefit that you don't have to commit your phtos to iPhoto before you can work on them.) At first I thought this application was overpriced but the more I use it and appreciate both the things it can do that other programs can't and the immense flexibility, the more I think it is well worth the money.
