If you ask me, i am a big fan of prepaid mobiles, the best thing in prepaid mobile is.. i can budget properly, i don't have to cram the moobile bill somehow in my budget ! Maybe the idea comes from here but now you have Pay-As-You-Go computers, or simply speaking Prepaid Computer. The flexibility of the pay-as-you-go model is also well suited to the economic realities of emerging markets where many people work in informal jobs with unpredictable paychecks.
In Frederico's words:
Sometimes great ideas are not feasible in practice, but the pay-as-you-go PC project proved quite the contrary. All the machines that we made available for sale in this initial stage were sold. In some cases we even had waiting lists! Even more important for the feasibility of the project, the level of PC usage by clients is meeting our initial expectations.
