I had to say DS, because it's really innovative and has a library of a lot of stellar games. The PS1, I remember getting when I was like 7 years old, so it's greatness has stuck with me for all this time. Not to mention, you can play it in the car with official hardware, and it has a lot of awesome games. For the third one I picked N64, although PS2 or Wii could have held that spot too. I guess childhood memories, as well as a number of over the top games motivated me to pick the N64. I didn't pick Wii just because it's too new, and it could end up the worst console ever, or maybe the best. So far it's looking pretty great.
