Heikki Karjaluoto, 2003, studied the Factors of Factors Affecting Consumer Choice of Mobile Phones, Purpose is To study Factors Affecting Consumer Choice of Mobile Phones and his result showed That The statistics reported are the means, standard deviations and the statistical significance of the mean differences. The results show that white-collar workers value enhanced data and networking features significantly higher than students and blue-collar workers. The only exception is the design, which is considered equally important between white-collar workers and students. This result seems quite reasonable, as it can be expected that white-collar workers can utilize these features better in their work than blue-collar workers. The fact that the importance of networking features, such as e-mail or WAP services, is not more valued by student is somewhat surprising.
