A study released during the WWW 2009 Madrid conference, which debates the evolution of the web, looked at the ways mobile search users differed from computer-based search users. By comparing Google searches on computers, iPhones and conventional mobile phones, the researchers found that the average mobile user was much more focussed than the average computer user and was more likely to search for the same type of information repeatedly, while users of high-spec devices (such as the iPhone) searched in a similar way to computer users.
