Dx0
Just installed their trial and I am very impressed. But I wouldn't use it to organize photo lobraries. For that purpose I still find IPhoto and Lightroom to be the most practical. Aperture being too slow on anything les than an 8 core Mac Pro.
DxO does a great job at fixing photos but is very, very slow. Also, you can't switch between manual and automatic mode without restarting the program. Still, great for fixing most RAW pictures.
