In the last decade the majority of the people around the globe have purchased and used mobile devices in their daily lives. Over the years the mobile experience has been described as taking over and possibly eliminating the web experience. However, this did not happen and the stats show that a large number of users are still using desktop browsers to book flights, rent Airbnb space, and purchase products online.
