I have been a computer geek since my teen years. On my early days, I learned to program on a TRS-80 Model 3. It literally had no ability for any graphics; it was all text. We saved data and programs on cassette tapes, which predated floppy diskettes. Yes, you read that right. My sister got the first legitimate computer in our house which ran MS-DOS. This computer had a handle and its own screen. Toshiba sold it as a ‘portable’ only because it was completely self-contained. I don’t believe that this computer fit in any backpack I’ve ever owned, and it weighted about nine pounds.
In high school, I carried a lot of books. I lugged around both a backpack and a purple duffle bag with school colors. Once I entered college, I continued to carry more weight than I needed to, opting to keep books or other items with me in case I wanted them. This included music in the form of cassettes, and later CD’s. I opted to be prepared at the expense of lugging all that weight.
