I loved my 2600. I especially remember CircusAtari (the balloons), Pac-Man, and Pitfall (like Maelakin). I also remember my parents' comment that these things were for kids, and that adults could simply not compete.
Anywho, no C64 or Amiga for me, no Coleco either, though I played on a friend's regularly.
Atari of course gave way to the NES, which was truly amazing at the time. I still remember long hours whiling away at Metroid, Zelda, and many other games. *sigh*
