I'm not going to get into a discussion about falling iPhone sales, it's all over the tech media and on this site. My question is, will Apple finally start listening to its customers and the market in general or is Tim Cook going to keep being the ostrich that he is and keep his head in the sand? The days of small upgrades and exorbitantly priced iPhones are surely over. There is only so much you can milk a cow before it says moo and gallops off. If this is not a wake up call to Tim Cook that the iPhone is not immune to declining interest then I don't know what is. But, if Cook doesn't take stock now, the iPhone's days are numbered.
