I’ve found that Aperture really did revolutionize my RAW digital workflow. I used to loath coming back from a shoot and digging through and editing all the photos.
I found Lightroom to be a poor rip off of Apple’s Aperture with a paricularly terrible user interface.
Besides, when the time comes for deeper post processing you can just set Photoshop as your default external editor and send a non-destructive version of the image out. As always, Apple set a new bar for revolutionary and progessive concepts and techniques in digital content and management applications.

And as I stated, Lightroom feels like a cheap imitation. Still for deep and highly advanced post processing, Photoshop is still the most powerful solution.
