PS3 and game development

I have just seen one of the best game development tools around and its on a PS3, Little Big Planet, you develop the game and levels for people to try out. I imagine this could be a great way of introducing students to game design and storyboarding and development. I want one. Wonder if I can get school to get one, we have an xbox360 and a wii already, why not cap it off with a PS3
