I've been using it to replace things that I used to do for personal projects in photoshop/gimp. Remove a background, add a person, put a letter in here that looks like the same crayon as the other letters.

Things that would take me an hour or so the old way takes three minutes with NB.

But I can see this applying to small businesses. Something that some random person would have to spend on hour photoshopping can be done in a few minutes with NB.
