One area where I think camera makers could really improve is in coaching people how to take better pictures. I'm sure there are some good mobile apps out there but as a casual camera user, I would love to take my camera off auto-mode and actually learn how to use the advanced features. If I'm shooting portraits or landscapes, it would be great if the camera could intelligently let me know, "Why don't you try this exposure/aperture for a better picture". Pretty soon I would start to learn on my own.
