I was in high school before I touched my first computer. It was a teletype attached via acoustic-coupler modem to a PDP 11 in a local university computer room. I'd sneak in there on Sunday mornings because that was the only time I could get enough core to play the text Star Trek game (printed on reams of teletype paper).
The first computer I fell in love with was the Osborne 1. It had a built-in 5" screen and two floppy drives (single-sided, single density), and came with software for only $1799. Unfortunately, I couldn't afford it. I did ultimately save my pennies and buy a Compaq Portable, which had a built-in 9" screen and two double-sided, double-density floppy drives.
The first thing I bought for my Compaq was a modem. This was the future. I met the one who is now the Unidicted Co-Conspirator on a local BBS. She was logged in via VT-100 terminal. We ended up starting our own FidoNet BBS, which ran until the mid-nineties.
And now, I walk around with a computer on my wrist that talks to a computer in my pocket that is constantly in touch with the world. I can raise my wrist and ask any question, and get the answer almost instantly. I have access to the world's greatest libraries, greatest minds living and dead, greatest works of art, literature, music, poetry...
And I use it to argue with strangers about minutiae.
