There are many predictions in it, however some of them are really amazing like
1) Implanted Bluetooth ear and Microphone
2) Some (rich) people will pay to be disconneted
3) Non human (objects, animals) will generate more data than humans
4) All urban areas will provide free Wimax connectivity
5) Keyboard dimension and screen size will be no longer the limiting factors as it will be replaced by new input and display technologies. ( i guess it will be sixth sense devices)
