In this exploratory study, we look into the emerging usage of Personal Information Management (PIM) applications on mobile devices. We collected data in two rounds of empirical investigation: first, with pilot users in an organization providing PIM services, then, in customer companies subscribing to these services. Our findings suggest that the benefits of PIM applications are mostly related to the users’ personal work: planning schedules and work tasks, making mobile communication even easier, and increasing flexibility, and that the benefits for companies are mainly realized through the users’ benefits. There are, however, still a range of barriers, ranging from difficulties in use and technical limitations to organizational level security concerns.
