Tecnology has changed a lot in the lasts 20 years.
When our parents were young, they didn't have computers and their mobiles phones were more simple than the ones we have. As soon as the first computers were designed, people got interested in the subject and started doing research for improving them. Then, as a result of the first devices' popularity, industry started producing more electrical appliances.
Nowadays, we have a high number of those machines but this is nothing compared to the number we will have in the future.
There are some articles explaining the mobiles development, and they say we will wear our phones on our wrists like we do now with watches.
