An increasing number of companies are trying to secure sustainable competitive advantages by successfully expanding their digital platforms. However, few studies have explored how the usage behavior of an adopted smart device (e.g., Apple’s iPhone) influences the extended adoption of its associated devices (e.g., Apple’s iPad) on the same digital platform. To fill up this knowledge void, we attempt to explore how inertia mediates the effects of user satisfaction, habit, and switch cost on the extended adoption of associated devices. Here, user satisfaction, habit, and switch cost are derived from dual model and habit perspectives, and inertia is derived from a status quo bias research stream. We found the key mediating role of inertia by analyzing data from 228 respondents who are using a smartphone. In other words, it was validated that user satisfaction, habit, and switch cost are key antecedents of inertia, and inertia both directly and indirectly influences the extended adoption of associated devices.
