The business world is silently undergoing yet another tectonic shift - from Web to mobile, or m-commerce. This title lays out the next generation of business models and the architecture of enterprise applications that will succeed the tethered PC-age. It helps readers imagine the possibilities of having a desktop PC in your hand. It is intended to be both strategic and business orientated, explaining why rather than what or how to. The book is also designed to be a definitive roadmap for the practice of business strategy in a world transformed by mobility. It builds on the authors' prior work in leading edge e-commerce and e-business, analyzes best business practices, and sheds light on what works and what doesn't work in the mobile economy.
