One of the things I was previously dissatisfied with in Aperture was RAW conversion; to the extent that I often used Capture NX2 in this process particularly for prints. It's early yet, but Aperture 3 seems to have made some significant improvements in their RAW conversion engine, particularly appearing to be a closer match to NX2, particularly if one incorporates Nikon style presets into the process in Aperture. As I look at this more closely, I will report more, but I am not the only one who thinks so. Interesting post here comparing Aperture 3 RAW conversion to Lightroom 2.6
