Here's a picture of the man considered to be the inventor of the cell phone, Martin Cooper. Look how large and clumsy that first phone looks in his hand. He's 81 years old now. The first words he uttered on April 3rd,1973? "Hello, Dominos, I'd like to order an extra large with anchovies." (OK, just kidding about this).
I saw him interviewed recently on "60 minutes," and he seemed like a very humble man.
