I said it before, and I'll say it again. Lightroom 2.

Lightroom 2 takes all the hassle out of dealing with RAW files. No extra steps!! It loads and treats all supported files the same. RAW, DNG, JPEG.. Doesn't matter, the interface is the same no matter what file type you are dealing with.

Worried about RAW files taking forever to load? Lightroom 2 takes care of that too!! You can choose to only make minimal previews when you import your photo's, only when you want to view an image larger does it load a larger preview. This allows you to quickly go through your images to make your picks, compare similar images, or trash the ones you don't want.

I'll say it one more time. Lightroom 2.
