Apple’s cash pile is now $178 billion, enough to buy IBM (IBM.N) or the equivalent to $556 for every American. Apple Chief Executive Officer Tim Cook said the Cupertino, California-based company would release its next product, the Apple Watch, in April. Apple Chief Financial Officer Luca Maestri told Reuters in an interview that the company did not sell more iPhones in China than the United States, despite some earlier predictions by research analysts.
