Photo management software for Windows makes us weep. For most people, photo management consists of loading the software (and drivers) that came from the camera manufacturer. So you've got a Nikon camera, and the photo management software is really different from your significant other's Kodak software.
It looks different. It acts different. It's easier to set up some ways, or more inflexible in others. It might even be installing extraneous applications on your machine you weren't expecting.
