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: Two Studies from Finland, 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.
