I almost always shoot in RAW... Just one reason is that I like the capabilities of Adobe Camera RAW to do some initial editing of my images.
However, when I am shooting with my iPhone or opening images that my wife has shot with her P&S, I don't have the opportunity of initially processing RAW images. BUT.. I can have many of the advantages of RAW shooting in opening the JPEG images from my phone or my wife's P&S camera when I select the Photoshop CC Camera RAW Filter...
I really like being able to adjust the images to reduce distortion.
Of course adjusting white balance with the eyedropper tool as well as many other convenient editing tools make the Camera RAW Filter a very handy tool!
Actually, I just noticed this filter a short while ago - probably because I edit JPEG images so seldom. I wonder if everyone knows about this filter
