Resumen
This article discusses differences between mobile e-commerce (MEC) and the traditional wired Web architecture. It offers an in-depth analysis of the various business models that have emerged in the MEC environment. It also presents a classification scheme, examines the relative strengths and weaknesses of the models, and discusses developing trends and their implications for MEC in the brokerage industry. The emergence of MEC promises to supercharge and extend the capabilities of mobile brokerage service, acting as the catalyst for further innovation. Although MEC proves advantageous in terms of ubiquity and localization, the wireless architecture presents a number of unique challenges. In the conventional wired Web environment, devices, applications, and networks are well developed and standardized. The wired Web architecture is comprised of four main components: Web servers, network transport, applications, and devices. Web servers facilitate requests for documents, which are transmitted using the network transport.

Resumen
The article discusses the impact ubiquitous computing will have on social issues like individual, group, and organizational behaviors. Aware and responsive customer relationships require a great deal of knowledge about the customer as well as access to the current customer context. This necessarily creates a need to provide personal information to internet service providers. According to the article, the potential scenario of sensors in one's bathroom and mobile devices reporting every move to remote service providers naturally inspires grave privacy concerns. While privacy will be an increasingly important concern, it will also present new business opportunities for privacy management services rather than insurmountable obstacles to the kind of services described earlier by the author. Already, a variety of products and services exist in this area, including encryption products enabling secure e-mail to privacy auditing services that certify companies' compliance with their privacy guidelines, and phone services that block telemarketers. Nevertheless, businesses wishing to explore the opportunities by expanding customer relationships must think carefully about the information they collect, who they will share it with, and how they will use it.
