I see your point that the video fits the actual usage style. But I had two issues while playing the video. 1. The volume was too high. I wanted to mute the video first before adjusting my system's volume. 2. I wanted to pause, check out the features mentioned in the video for a while and then resume the video. So I did need the controls. They can appear only on mouse over so that the feel of a live demo still remains.
