What is wrong with the ripoff? It's not an exact copy, and it's still in a slightly different market than Apple is. If someone took a deceptively similar coke can and converted it into a speaker, would that infringe on Coca-Cola's look & feel? Microsoft ripped off Apple's windowing look & feel, and Apple ripped it off from Xerox's Alto.
