What are some recent product introductions that failed the four rules of product development discussed by our textbook authors on pages 230 to 232:

(1) Is it easy to duplicate? (2) Is it easy to understand? (3) Is it unique? (4) What is the emotional bond the innovation will create, and will it be a lasting one?

You are required to discuss one example for each of the four rules, but that example can be different across the four.
