My "upgrade" from 20D to 5D thoughts

I find the images surprisingly sharp from the 5Dc, probably due to a weak AA filter, and downright pleasing in their tonality. I also have a 5Dii that is OK, but I generally prefer the mellower images from the 5Dc. Having grown up in the film era I find many of the newer camera's features interesting but not very useful for the way I shoot. I do miss sensor cleaning and micro-calibration.
