For me there is a time and a place for both. I don't know that the picture in the OP was the best example of the difference because it's easy to get the result of the 'B' photo with a jpeg and free software (I use Picasa). Maybe that is why people are feeling a little contentious.
I don't EVER see myself shooting all RAW. I HATE having to process EVERYTHING. I want to snap, upload, hit "I'm feelin' lucky" (which works perfectly 95% of the time), and get printed or blog. I only shoot RAW in weird lighting, portaits for other people, and low light.
But that's just me
If you want to shoot RAW all the time or jpg all the time... knock yourself out
