Microsoft’s private company meeting at Seattle’s Safeco Field was a hit, with a preview of a “Bing 2.0” overhaul or here, demonstration of Project Natal, unveiling Windows 7 television ad. And then Steve Ballmer spotted someone at field level, allegedly a member of the Windows group, using an iPhone to take his picture. Ballmer grabbed the Apple device and made some funny remarks, then put it on the ground and pretended to stomp on it, before walking away, reports. The scene was visible on the big screen, so even people in the upper deck could see what was happening. Later, during his presentation on stage, Ballmer referred to the episode again, teasing the person and making it clear that he hadn’t forgotten what happened. Microsoft employees alluded to the incident on Twitter.
