I agree with the idea, just not the location. A mall kiosk would get to exposure to those who actually know your product, But I wouldn't remain in that location very long. Typically my wife (when shopping in a mall setting) tend to avoid these kiosks. Also while walking by, some of these kiosk vendors are playing with the devices or trying to pressure sale the products. Again I would use the mall location as a test run only then move to a more permanent location.
