Global trends like an increasing amount of knowledge, creativity and innovation related work, lead the market for mobile business applications to a continuous expansion at an unprecedented speed. However, up to now, it remained unclear which factors are relevant for technology acceptance and adoption of mobile business applications. The present paper fills this void and provides insight into a new field of technologies (i.e., mobile business applications). This study integrates a variety of enabling and inhibiting factors, such as convenience, perceived quality, ease of use or usefulness, in a theoretically sound and empirically tested model. Moreover, we investigated whether users from different generations have the same or varying reasons for adoption new mobile business applications.
