I wrote my first college paper on a new Smith Corona electric typewriter and my last on an Osborne compact word processor. I started graduate school with a turntable and ended with a compact disc player. When the boys were born, I took their pictures on film that had to be sent away to be developed. The pictures came back to fill albums and shoeboxes. When the boys graduated from high school, I uploaded the photos to my computer and posted them on Facebook.
