This sounds s cool, but is even practial....even in the future? Where will the camera be? Would it replace the cell phone? Is it safe? Could it be hacked so that others can listen in on your most personal calls? Will it replace the home phone? Cheap enough so that everyone can buyone?

I think the finger video phone is nothing but an advanced version of the phones we have now. So in a way it will not realy replace the phones we have now it is only a different type.
And either way I dont think hacking it will be a problem either. It will only be like doing things on a computer today. Im sure they will probaly have norton anti-virus or something on them so you have nothing to worry about.
