Why would you even say that? Work for ADOBE much??
While Gimp has a lot to be desired, on a basic level it does the same thing. If you don't believe me-
"GIMP is a freely distributed program for such tasks as photo retouching, image composition and image authoring. It can be used as a simple paint program, an expert quality photo retouching program, an online batch processing system, a mass production image renderer, an image format converter, etc. "
"Adobe Photoshop is a ...graphics editing program used for image creation, motion graphics editing, and advanced image analysis features."
While Adobe Photoshop is far superior in many ways it doesn't have to be that way. "GIMP is expandable and extensible. It is designed to be augmented with plug-ins and extensions to do just about anything."
