Mine, in rough order, are:
I remember when our high school got macs in the library around 1987. I would sit there and drag and fill ovals and circles for as long as they’d let me. It was mesmerizing.
The first time I used a word processor I remember thinking. ‘You can make as many mistakes as you want and it doesn’t matter!’
The WWW was a real eye opener. The first time I surfed the web was around 1995. I was enthralled into the wee hours of the night even though the content was primitive, banal, and completely random.
When I ripped a song off of a CD, ejected the CD and then played the song off the hard drive. I remember thinking: ‘Oh man, this is going to be huge.’
The first time I saw a 3D video game was a TV spot for Super Mario World. Mario was running up and down a staircase with the camera view over his shoulder. It was amazing.
The first time I used video in internet chat. I was like, “Oh my god, this is crazy.”
In Google Earth I have an add-on that tracks commercial jets in real time. Once, Google Earth displayed a jet flying right over my house. At the same time I could hear the pilot conversing with the tower via a web page that streamed air traffic control transmissions. I stepped out onto my balcony and looked into the sky. Sure enough, there I saw that very jet streaking across the sky.
What have been your “Wow!” computing/information age moments?
