I got my Atari 2600 for Christmas 1983. I first remember seeing one the previous year at a friend's. At the time, I wasn't aware of any other consoles existing. I did have an Intellivision much later but like you, could never really get used to the disc controllers. I'm still amazed at how long these consoles were produced. Atari produced the Atari VCS/2600 until 1992. INTV continued producing the Intellivision through at least 1990.
