You can't always finish what you started. Even those responsible for some of the most important inventions of our time must sometimes back away and let somebody else take over their creations instead. Sometimes, other people can do what you do better than you. At least, that's the situation that the Eastman Kodak Company has just found itself in the midst of. The company will stop selling its own digital cameras, even though it was the one to invent them way back in 1975.
