"The iPhone is made, of course, by Microsoft's longtime rival, Apple Inc. The device's success is a nagging reminder for Microsoft executives of how the company's own efforts to compete in the mobile business have fallen short in recent years. What is especially painful is that many of Microsoft's own employees are nuts for the device.... Mr. Ballmer snatched the iPhone out of the employee's hands, placed it on the ground and pretended to stomp on it in front of thousands of Microsoft workers, according to people present." - Christopher Chung

"Despite Mr. Ballmer's theatrics, iPhone users are in plain sight at Microsoft. At the sprawling campus here in a Seattle suburb, workers peck away on their iPhone touch-screens in conference rooms, cafeterias and lobbies. Among the top Microsoft executives who use the iPhone is J Allard, who helped create the Xbox game console and is chief experience officer for the entertainment and devices division." - Christopher Chung
