Continuing in the spirit of "simplicity", I recently came across a program which seems to yield great results, and very much simplifies my workflow. It is called "DxO Optics". I'm not sure how well known it is, but if you haven't seen it in action, I would strongly recommend trying out the demo version.
The "proof" for me came when I re-processed the "Rosebud" shot. Apart from correcting the lens distortion, this also pulled out more details in the light and shadow areas, and the overall result seemed to have a higher quality in colour tone and level of detail.
My six most recent shots (at time of writing) were all single exposures processed in DxO Optics, then finished off in Photoshop. I was very impressed with the results, even though I actually spent a good bit less time in overall post-processing.
Well worth a look at the demo version: DxO Optics [link]
