Microsoft CEO Steve Ballmer wants to outdo Apple in the sheer number of retail stores but has been held back by poor results at what few stores he has, according to sources. Both the executive and COO Kevin Turner would want to pass Apple's 300-plus store count but have had to keep their plans on hold. The stores are designed to mimic Apple's design, which is meant to serve as a halo for the brand, but don't have the according traffic, SAI learned.
