M-commerce has many aspects from design and usability of the devices to monetization issues of mobile applications. M-enterprise is about drastic changes in internal and external communications and efficiency in the work of each business unit. M-industry reviews the impact of mobile technologies on traditional industries and the development of entirely new industries. M-style is how our everyday lives are changing in behavior, choices and preferences. After reading this chapter you will be able to differentiate m-business in many important areas: why is it important, where it is going, what is the value to consumers.
