Logitech: "A recent Logitech study revealed that people, on average, have six applications open on their computer at any one time, and the active window switches or a new window opens every 50 seconds. To navigate the vast content at their disposal, people spin their mouse´s scroll wheel approximately 26 feet in an eight-hour day."
I crunched a few numbers and it turns out that with my mouse and with my monitor set to my screen resolution, the 26 feet of scrolling translates into 330 feet (slightly over 100 meters) of on-screen content a day (one full mouse scroll moves the slider about 15 inches as measured with a ruler).
