We studied consumer attitudes towards different aspects of mobile peer-to-peer services by administering questionnaires to Finnish consumers using advanced handsets (N = 196). Most of the intention to use non-established services did not materialize as actual usage. Music and software downloading attracted most payment willingness. Legal file sharing stood out as a promising new business model. Respondents estimated battery consumption of different services reasonably. Respondents were more sensitive to increasing energy consumption than delay in different service designs. Respondents were willing to share content, presence data and location data with 30-50% of their active contacts.
