question of the weekend: Atari 2600 or Commodore 64?

I got into a bit of a chat yesterday on Twitter about what which computer you had as a kid said about you. (Obviously, this would mostly apply to Generation Xers, unless you were a very sad child born in 1990 who had only garage sale leftovers to play with around the turn of the milliennium.) Absolutely no conclusions whatsoever were reached in this matter. My own general and vastly unscientific view is that it seems that those who had Ataris in high school went on to become PC users, and that those who had Commodores went on to become Mac users. This may be based entirely on the fact that I had a Commodore and am now a Mac snob, and my best friend Allen had an Atari and now actually thinks PCs are cool.

Which computer (if any) did you use as a kid? Atari 2600 or Commodore 64? Or one of the less popular ones: Sinclair, Amiga, Intellivision, Odyssey2, something else? (My first computer, before the C64, was a Texas Instruments TI994/a. I loved it something awful but quickly outgrew it.) Do you suffer today from platform nostalgia? And just what the heck does it say about which computer you used as a kid?
