Most people yell at their computer. Preciously few people who spend 6+hrs a day on calls and meetings, get a good headset with a boom microphone. Nobody correlates the "what? Did you say something" and overlaps and garbled voices and muffled noise cancelled uni-directional simplex conversations on them not getting a company-expensed headset. Improving on the built-in laptop video is not even on the radar :D
