Windows 7 beta testers are disputing whether or not Microsoft's is paying attention to their feedback. The argument follows a blog post by Steven Sinofsky the man in charge of engineering the new Windows 7 operating system. He notes that in one week in January Microsoft received data through Windows 7's automatic asessment system every 15 seconds. According to Sinofsky, it's impossible to keep everyone happy. That's partly because there are only so many changes Microsoft can perform to the system and still complete it, and partly because in many cases testers often have opposing views about a feature."
