The EIAA (European Interactive Advertising Association) has proved in a recent report what we probably could have guessed ourselves. People who own wireless computers (such as the one I'm using right now) are very likely to do things such as contribute to websites (such as this one), make/spread user-generated content (like this), and review/rate content on websites like YouTube. On average, people who own a wireless laptop/device spend 18 hours a week on the internet, as opposed to 11 hours that the average wired user would spend. This is because, you guessed it, wireless users can bring their computer with them, instead of having to come to it.
