Is this to let the user actually do things to RAW files in camera that you would normally do on the computer?

If so, I would say no, purely because whilst I am out with my camera I would rather use the time to take photos and so the processing when I get home. Also, even with the new big and bright screens we have on our cameras now, I still couldn't confidently make any changes in camera. I have taken many pictures that have looked good on the screen, even when I zoom in, but when I get them uploaded they often turn out to be not what I wanted.
