So yeah, I'm a little behind the times on this front.
Anyway, playing with Lightroom beta4 now. It supports the raw output from my camera, and is smart enough to understand Raw+JPG shooting mode (which, oddly enough, the software what came with my camera seems confuzzled by). It has a nice selection of basic image adjustment tools (colour correction, exposure compensation, crop/rotate, shadow/highlight recovery, etc...) and supports a very 'natural' photography workflow. I must say, it's a nice one to use. I might have to go out and purchase this once it becomes final.
