Often high costs, especially compared to the costs of the “fixed” Internet, were given as reasons for this. But considering the prices businesses, and more and more private people, pay for mobile voice and email connectivity, other reasons must exist for the reluctance to use mobile applications. One reason seems to be that quite a few people are not convinced, that mobile access or receiving information on a mobile device adds value. More formally speaking, usefulness or a relative advantage are not perceived, especially when the ones receiving the information are busy decision makers, who have other things to do. Especially when confronted with the still existing weaknesses of mobile devices, e.g. their limited I/O-capabilities they may see mobile work as mobile stress with no sustainable use. In this situation, Jan Muntermann has thought about possible contributions that Business Informatics can bring to the table, and decided to aim for an example of presenting decisionrelevant information and to show its use as well as its technical feasibility: He analyses the use of immediately receiving selected ad hoc messages to be able to buy and sell affected stocks quicker than other market participants.
