> Now I'm not a user of this feature. But in my immediate circle, no less than 6 of the many people I know work with windows (maybe 30 folks ?) use the task bar on the left or right (they have different monitor setups)

Even just different monitors. While supposedly both are 16:9, my main monitor and my laptop have very different proportions. The laptop feels cramped vertically, so I move the taskbar to the left edge to have more space. Guess I'll autohide it when I upgrade.
