As a pro photographer for nearly 30 years, I find that I shoot digital in precisely the same way I used to shoot transparency (which couldn't be fixed up in PS if you screwed it up). That is, I try and get as near as perfect I can in camera - correct exposure, good lighting to bring the image into the contrast range the medium can handle (without having to pre-flash the film) and as close to final composition as I can (assuming I've been given a finished layout by the art director or client). I do tend to shoot a tad wide to allow for different croppings.
Frankly the less time I spend on a computer the better. And I like my images to look as natural as they can. But then, my main area is food photography and you can't f*** around with food the way you can with people
