The numbers we are already seeing with regard to smartphones and tablets is staggering but it is only just beginning. Soon, most people on this Earth will have smartphones and multiple tablets.
By 2015, many people will have a tablet for home, a tablet for work, a tablet for the car (soon to be mounted in dashboard and integrated with car) and another couple extra tablets such as in the bathroom and out on the patio. All these tablets will be linked together through the cloud so as soon as you update a contact, purchase an e-Book or an MP3 music file, all your other devices will be instantly updated so it will be transparent to you what device you are currently using. All your data will by synced.
We are going to see some trillion dollar companies (in terms of market capitalization) within the next decade. Apple, Google and Samsung to be sure. Likely others too.
In your world little real work will be done. Just people tripping on themselves, dicking around on pad devices bouncing oh so valuable information around. Like telling their microwave to start cooking that turkey loaf TV dinner. Meanwhile the Chinas and Brazils will be creating tangible items of value such as food, mined minerals and manufactured items. Who wins in this scenario?
