Changing Technology New and Old

As we move forward with different technologies such as smart phones and various kinds of smart tablets. Old technologies still hang on.  The Washington Post reports that Google TV is upgrading.
So what?  I guess I find it interesting that television and radio still exist.

The pantelegraph

(http://courses.washington.edu/pioneers/images/petograph.jpg) 

One hundred years before I was born, Abbe Giovanna Caselli invented the pantelegraph in 1862. The pantelegraph transmitted still pictures over wires. Of course, there are many inventors before and after Abbe that created what we know as television.

What is my point?  We have the iPhone, Android phones and such but these are always changing.  What will the new technology look like in one hundred years.  I mean, we are way past Dick Tracy's watch phone.  How many of our current technologies will still exist?

Radio still exists but now I can listen when I want.  I don't have to warm up the crystal set to listen to my favorite show.  All I need to do is to subscribe to the podcast and the show is waiting for me but it is still radio.

I wonder if the iPhone and iPod will be as important as milestones in one hundred years or will whatever is current in 2111 be something that does not see its roots in TV, radio or the telephone?
                                            How will we network socially?      
                                     
                                       I just hope we don't go the route of Johnny Mnemonic!
