I learned "Computer Science" in junior high on an Apple 2c and moved to an IBM when I had saved enough money from 4 years of after school jobs, lol. I just thought the IBM product was better and could do more of what I wanted to do with a computer.
I also think it is funny that the video just happens to be 4:20.
