I wonder what the latency of low quality products is? Apple wouldn't be the first company to go through this - I can think of car and clothing manufacturers which were known for quality only to abuse their reputation and eventually lose sales, sometimes catastrophically. I wonder if there's some B-school stats or case studies which show how long customers are willing to give a business the benefit of the doubt and continue to buy products based on a company's old reputation before their new reputation takes over and sales drop?
