1. INTRODUCTION
The Latin American society is divided by stratification and, We have analysed how some of the elements of user opposed to the system of welfare in developed countries; experience, taken from Hiltunen et al [1] and Roto [2], are there are very big differences between the poorest and the richest. The upper stratums of the society have a standard of living as the one in Europe or North America and the lower stratums have a very different perspective of life: As described by Roto [2] when analysing the “ user needs they work hard on unstable jobs, they live with just the for internet on a mobile device”, there is not proven need money for the current day and they struggle for being able for the full Internet in the phone. This could be changed by to afford education or any other commodity after paying for analysing the cases where the internet can provide real value in situations where the only access is the mobile phone. As well, this will definitively increase in the case Only a small amount of the population has internet access users have the mobile phone as the primary place where to from their homes (i.e. Brazil, although being the country in access the internet. More about this issue will be discussed the region with most internet users, has only 6% of the population accessing it from home [17]) and this is usually associated to intellectual work or a certain educative level and economic capacity to support the expense that this The value of Internet is directly proportional to the value of represents. With respect to mobile phones, the situation is the services it provides. In developed countries people uses quite different: due to a rapid increase in the cell phone many internet services while in developing countries this offer and many promotional plans where phones where given for free when purchasing some other item; it has increased to the 70 percent of the Latin American Context:
