If you are happy with your cameras jpegs, then it pretty much ends the discussion for you. But to say that computers can't do what cameras can do is false. Some cameras sharpness and noise setting are applied to the RAW file and that can limit your results. The advantages of shooting RAW are: The ability to optimize the settings (sharpness, noise, WB, Exp, and so on) for the characteristics of each unique photo. The ability to control these aspects either 'locally' or 'globally' in a file helps you make the most of each shot and better depict your vision. If you think that a "One Setting Fits All Shots" approach works better for every shot than what you might get with independent control based on the characteristics of the shot, I would suggest you are mistaken. The optimal sharpness/noise setting is rather dependent on the size and manner of the 'output'. So if you are printing a couple of 5x7's or 8x10's to be viewed in the hands at arms length, or shots for the web or a 32x40 poster the optimal settings are not the same. If 'good enough' is what you have, then you needn't go any further. These settings, which directly affect IQ, have far more latitude on a RAW file than on a jpeg. Starting with a good RAW capture and using 'non destructive editing' you create the least limiting scenario. A jpeg file simply has less latitude, less flexibility, less data. In post you can sharpen and then set the masking level, which is something you can't do in camera. Every camera has a limited dynamic range, so in many shots you may wish to 'lift' the shadows, while in another you may want to recover some of the highlight range. This ability to 'shift' or expand the range of light beyond what you captured is very important. There are programs that allow you to adjust the sharpness of 'surfaces' or the sharpness of 'edges' but in all these cases it is 'adjust to taste' - So if you are satisfied with the jpegs you get from your camera, that's a good stopping point! For others, who seek to potentially maximize every discrete control point under their command (not just sharpness and noise) to produce the strongest image they can...Well those folks will ALWAYS shoot RAW. Once you master a decent processing software (LightRoom, Aperture, Silky Pix, DXO) you should be able to do better than your camera in most cases. The only penalties to shooting in RAW are the file size and the time spent at the computer. If you think you also loose IQ when you shoot RAW then you are a minority indeed!
