My bet is a device like google glasses (or contact lens) with a sleek headset that has mind controllable sensors. I don't want to type, or talk to control it. I just think of calling my friend and the phones dials, and I see her image. I am willing to carry the computing unit in my pocket so the glasses can remain light. I bet that it is 5 years away. If it is like the cellphone, it won't be google that builds it because there is just too much technology that is not yet ready/affordable.
