The first computer we had at the house was a Radio Shack word processor thing that my dad got from work. My programming highlight was finding a way to draw on its screen like an Etch-A-Sketch (it might have been in the user manual, or maybe I read about it somewhere). He'd transmit pages back to work over a separate modem that had the big foam cups, which is where you'd stick the phone handset.
The first computer I used at school was a black Apple II. This was in 5th grade (so... 1981?), and I got lucky by lottery drawing and attended a science/computer magnet school. The main computer lab had maybe 30-40 Apple II's, and there were carts carrying computers & monitors around the rest of the building -- although we may have had enough to have a computer in every room.
My parents got a used 386 of some kind with Windows 3.1 from a friend. I don't think they ever really found a use for it, though.
I used school computers of various types all the way into college, and never truly had a reason to own one myself. When graduation loomed (in 2000; I took my time!), I realized that I couldn't just keep using the school labs for everything, so I finally bought my own computer -- a first-gen blueberry iBook (300 MHz, 3 GB, 160 MB, 4 MB video).
I bought it in the fall semester of 1999, then got the AirPort wireless card & base station over Christmas, so I've been doing wireless internet for almost eight full years now. Apart from the battery not holding a charge, it still works, with its RAM bumped up to 540 MB and running Mac OS 10.2. Maybe someday I'll put in a new battery, bigger HD and the latest OSX that supports it.
It still can't do a lot of the things that my new 15" MacBook Pro does with ease, though.
My parents got a grape iMac (266 MHz?) and ran that sucker into the ground, getting a new monitor installed at one point, then a larger hard drive, until they finally were overextending it, wanting to store & edit digital video. They got an iMac G5 a couple Christmases ago, justifying it (and, finally, broadband internet) with home movies and the ability to easily video chat with my sister's family in Germany.
