I agree with your premise. It seems to me like many photographers are more interested in editing on the computer than in the actual photo-taking. I can understand how people would find it really enjoyable to sit at a computer for long periods of time, editing images. I am not one of them!
As for me, I want to "keep it real", at least as much as possible. So I don't use Lightroom, Photoshop, Aperture, noise reduction, etc. All I use is the simple iPhoto program that came already loaded onto my computer when I bought it.
My philosophy is, if I didn't get it exactly right in the camera, then I would rather delete the images, and go out and take more images, than try to fix a faulty image.
Why sit at a computer "faking" things when I could go on another photo trip and take more images instead?!
Tom, for a lot of types of photography yeah, I've been happy with the equivalent of an out-of-camera jpeg.
For a lot of others though, I became frustrated with the limits of the in-camera jpeg processing, things like the dynamic range challenges of many outdoor scenes. And so, part of my going for DSLRs was the fact that at the time that was the way to get Raw files, and I wanted those Raw files!
So, when I shoot things that would come out fine as jpegs, it is quick and easy to run the Raw files through say the Canon Raw software Digital Photo Professional (DPP) for a quick conversion, and I've done that and still keep the Raw files in my Lightroom library and am happy!
But DPP still acts like a "digital darkroom". It can read your in-camera settings for Picture Style and White Balance and apply them (with Contrast and Saturation and Sharpening and such) to your initial image preview, and so you have a "starting point" which will be "like the jpeg would be". Of course, though, with Raw you have the flexibility to change those things around and tweak them with greater latitude than you would with a jpeg and "normal" editing.
This is good stuff also because I have my camera "dialed down" to a Neutral Picture Style with Contrast and Saturation dialed down even more (to -4) because in scenes with dynamic range "challenges" using a Picture Style such as Standard or especially Landscape can give misleading "readings"/warnings of highlights, and they show up both in the histogram and in highlight "blinkies" -- same with Saturation and the RGB histogram. So, those settings come in handy when "Exposing To The Right" but can make for "dull"/flat tones out of the camera until you go to work with your Raw processing software!
So, yeah, my out-of-camera jpegs would tend to look fairly flat/lifeless without any Contrast/Saturation/Sharpening applied, but then a few tweaks and all of a sudden they can jook just as good as the camera could produce as a jpeg, and with a few more tweaks they can often look better
